how to downgrade from sonoma to monterey/ventura?

hi! i bought this mbp 13" early 2015 with installed sonoma using OCLP.

but since my keyboard and mouse were undetected (unless used with external keyboard and mouse), and it keeps on lagging and the fans frequently turn on, as well as it's getting warmer than usual, i want to downgrade.

i mostly use it for school purposes only.

I can't seem to find a guide here, mostly it's hard to follow.

I'll appreciate ur help, thankies!
