If there was a way to make more Bitcoin out of the Bitcoin you have, we would all have it staked or what ever.  But Bitcoin can not be staked and the only yield generating ways are non custodial.  Remember that pretty much all Cryptocurrencies with 'staking' feature are simply inflationary assets while Bitcoin is DEflationary.  You may not be able to stake it, but it will produce you more value passively as you hold it.
