Pick a way that is most convenient for you:

Using Saints Menu

Go to Tools - Saints Field to enable/disable functions you want

Using csc.rsp

1. Create file Assets/csc.rsp

2. Write marcos like this:

   #"Enable DOTween"
   -define:SAINTSFIELD_DOTWEEN_ENABLE
   
   #"Disable Addressable"
   -define:SAINTSFIELD_ADDRESSABLE_DISABLE
   
   #"Disable AI Navigation"
   -define:SAINTSFIELD_AI_NAVIGATION_DISABLED
   
   #"Enable SaintsEditor project wide"
   -define:SAINTSFIELD_SAINTS_EDITOR_APPLY
   
   #"Enable the code analysis"
   -define:SAINTSFIELD_CODE_ANALYSIS

Note: csc.rsp can override settings by Saints Menu.

Using project settings

Edit - Project Settings - Player, find your platform, then go Other Settings - Script Compliation - Scripting Define Symbols to add your marcos. Don't forget to click Apply before closing the window.
