generic question

hello

I own an RTX 2060 6GB.

what configuration should i do in unreal engine to use all available resource to use lumen?
and how do I save it to use in future installs?

what about the project: what is the configuration I should carry out?
And how do I make a basic project template so I don’t have to redo it every time I start a new project? taking into account materials and function materials?

Thank you very much
