if i reset/format my mac, will it remain at big sur or will it be updated to monterey?

Thanks, previous owner mentioned he can't reset as the os will auto update once reset and cracked app will no longer working on monterey (he left few cracked app).
I wish to reset this machine without having to update, there's so much I want to learn before jump into latest and greatest update available, also tend to have bugs unsolved yet.
Glad I ask here.

thanks. I'm doing it now.

solved already, the solution indeed kinda technical but I managed to make it work.

The issue was after full wipe clean the storage, upon setup, I can't create computer account, said I can't use the name. Trying to change here and there, but to no avail.
Found out that it happen after full reset of the system for many other user. The solution is as per link below. I was having trouble to understand the instruction as I'm not familiar with Mac to begin with.

fix macOS stuck at "Create a Computer Account"

Yeah, I'm also learning from here. Now I try to solve printing in black and white but it appears to out as colour. Using Epson L3150.
