Motherboard with dual BIOS?

I want to build a mining rig but the weekends i want to use ir as pcgaming.
Where can i find a mobo with dual bios?
Maybe it is enough with profiles? I would like to set one profile for mining (all pcie x1, etc...) And other profiles with pcie x16, only one gpu activec, etc.

Which mobo do you recomend?

I am crazy?

Ty all.
