Lossless scaling LeGo 2/LeGo S

I have the Legion Go 2 Z2 Extreme and a Legion Go S Z1 Extreme 32gb, want to try the lossless scaling to boost fps and smoothness in some games. Already see some vídeos on YouTube but don’t know the correct method to configure. There as a default like configuration for this devices that works on almost all games or need to configure each game separately?
