03 suburban disable low oil pressure

How do I disconnect this alarm. I know I have an oil pressure issue, but need it disabled. It is low pressure problem intermittent at idle.

I don't know, but when my 93 had this problem I increased viscosity from 5/30 to 10/40. Now run 20/50 and get 10psi at idle; 350k miles
