You can check this lists of
open Source Hardware Wallets. Note that ledger nano has open source software which is the Ledger Live, the hardware wallet itself only has a close source secure element. The wallet can be used with Electrum. But just that Ledger company also do not value privacy.
Thanks for the comment! I’ve looked through the list already, but to be fair did not find a really good alternative.

As for ledger - yeah, I know about data leaks and already have disposable number and email for the order

But yeah, closed source chip makes me a little doubtful
