How to stop attachment?

[12345___]

I have a 2 1/2 yr old black capped conure who has a really strong attachment to me and I was wondering how to like stop it / make it not hormonal?
he is very comfortable with me (sleeps in my hand, goes on his back, hangs upside down from me etc) but I think he has some like hormonal bond to me?
He frequently regurgitates (not TO me, but js around the room) - (I thought it was because of a big mirror in my room so I covered it with a sheet but it didnt stop anything after weeks so I kinda gave up and took it off)
I've found the only thing to stop it is to js distract him the whole time (talk to him, make noises, play with him, etc but i can't do that every time obv) - or I js put him in the cage and cover it so he can't see me'/the. mirror (which is hard when he can only be out for a few hours)
he also like overpreens (?) his feathers so they get all rustled up and like go outwards - its weird though he will stop for months or like a yr then randomly start doing it again with no changes in his environment - but I've never known what to call it because I can't find ANYTHING on like overpreening js the tail
he used to be fine with other people (especially my dad but then when he started being aggressive he kinda stopped going to talk to him so now hes only really around me) but now he's so aggressive to everyone except me - he bites them and is js horrible unless i'm in the room (excluding his babysitter when i travel who he is like angelic too its weird)
his conditions (?) are:
during the week he is outside most of the day (7am-4ish) and talks to the native birds in the area (lorikeets, rosellas, etc) and when i get home he is out for 2-3ish hours (and then like like tons 5-6hrs minimum on the weekend) then goes to bed at 7.30pm - but its not always quiet when hes 'asleep' bc sometimes I make noise when studying or have to watch videos and don';t have headphones (though I turn them down to like 20%
he has a flight cage the size of the picture below and lots of toys which I change every 3ish months and deep clean + buy a few new toys
he eats pellets and veggies daily in the morning/arvo (but not atm bc we don't have any)

All sounds like normal conure behavior. For the biting:

Biting, whether intentional or not, just over preening your skin or actually taking chunks of meat out - all are PAINFULL! In the wild that sort of behavior is not tolerated by the flock. They ostracize flock members who continue to act like that. We call it 'Shunning'. This WILL work, but needs to be done correctly to get the message across and it needs to be done IMMEDIATELY so the parrot can associate the bite with the shunning action. And it needs to happen every time and with anyone involved with the parrot.

When the bite or over preening occurs:

• Say in a forceful but not shouting voice "No Bite" or other endearments.
• Immediately place the parrot on a nearby, handy chairback. NOT the cage (that would only teach the parrot to bite when he wants to go back to his cage).
• Turn your back to him and ignore him for 1 minute. No peeking, no talking about or too him, NADA. NO eye contact. No less or the message is lost, no more or the bird will not associate the action with the bite.
• After a minute you can try to re-establish contact.

Rinse, repeat as needed. Most parrots get the message after a few times, some may need more. Also very important - make sure the bite is not your fault. Annoying your parrot, asking him to step up when he is otherwise preoccupied with eating or playing, bothering him during known moody times like mating season, or ignoring the warnings and body language of your parrot - these are bites that you deserve! Learn, and be a better parront !!
