I need a bit of help with my game. i have LSPDFR installed with various others mods such as traffic policer, call out manager, Spike Strips and others. I play with my PS4 controller. i would like to know how i can disable or delete all the default GTA V keybindings for the keyboard as the default keyboard controls conflict with my mod controls; i would like to map the controls of my mods to my keyboard

To change GTA V keybindings, you would need to do it in GTA V game via Options.  I'm not sure if it'll just let you completely remove controls, but you could try.  Maybe just change the ones you have conflicts with.

To change controls for your mods, you would need to open .ini files with the notepad.

 

It all comes down to your keybind management.  I don't think any of us will be able to help you sort it out, just select keys you are comfortable with that don't overlap with anything else.  I'm running a ton of mods/plugins and I have no overlaps.
