I want a module, where I can scan my finger and my personal profile unlocks, when my bro is using it, he can open it with his finger.

This is a art of Face ID that I want. But with Fingerprint

Is this possible to make? When yes, how can anyone create it for me? I would pay for it.

Here is a this fingerprinter I want to use:

I’ve gotten away with 2.4A on a Raspberry Pi 3B+, but that’s riding the edge of acceptable.

Oh that’s a great idea to use a battery for that! Thanks!

Unfortunately, no. My recommendation is to find a raspberry forum, or search Google. Changing something to a default isn’t specific to that one microphone, it probably applies to many others. Might be an easy thing to fix.
