Holding a British passort (not BNO) in Hong Kong, how do i move to Britain permanently : immigration

Hey guys, I maintain a Hong Kong passport and UK passport( as British citizen not BNO), simply need to know if there are any procedures that I have to undergo earlier than I transfer to there. I learn many pages on gov.uk. There are not any pages that talks about my case.

Mainly i obtained my citizenship by British Nationality (Hong Kong) Choice Scheme:
