Is there a way to make the changes to certain values in the game permanent? Like I wanna permanently raise the HP cap from 9999 to a million and I wanted that change to persist even after the game's restarted.

That depends on how the game was made. If it's compiled directly to machine code (e.g. C/C++), modify the binary itself. If it's compiled to some intermediate representation, you'll need to change whatever that intermediate representation is. e.g. unpack javascript code from an asar file, decompile Assembly-CSharp.dll into C# code, etc.

Maybe it would be easier to make the modifications you want to max health before you load the game.

Yes, as mentioned, this will depend on the target. It will also depend on what you are actually wanting to do. There are hard-coded modifications (e.g. permanent modifications to the executable), or soft-coded modifications (e.g. temporary modifications to memory).

You can create a launcher that will apply memory modifications at startup (so that nothing needs to be done on your end). Or, you can create a table/trainer/memory patcher etc. that will apply the modifications whenever you decide (but will need to be applied by you, each time).

Hard-coded modifications will vary, as described. I usually use x32/64dbg for that, but not usually for cheats.
