How to delete a .plist file on Monterrey

So I just updated my Macbook Pro 2011 (8,1 Model) to Monterrey and went charger is conected everything is ok but when I try to use it only with battery it get laggy and slowly impossible to work with, as soon as I conected again it gets fluid again.

Looking for an answer it seems there is a problem with a file that checks model or something like that, but the file is a .plist it seems in older versions of MacOs you could deleit as simple as any file but know its blocked.

Hoping anyone of you have a solution for this or for the laggish issue, thanks in advance
