I am using encoders to adjust feed override and spindle override, I need these values to remain at 100% whenever I start LNC, how can I do it?

Depends on your HAL setup, but you can include something like:
setp halui.feed-override.reset TRUE
in your halfile.
If that winds up forcing the value to stay at 100% all the time, you can set up a one-shot component that is triggered by the machine-on signal. Something like:
Note that if you have the little encoders with built-in pushbuttons and you want to use them to reset FRO or SRO after the machine is on, you'll want to pass the machine-on 'trigger' through an or2 component. That way both the trigger and the encoder button can reset the override value.
Same-same for the SRO; use another or2 component and the same machine-on trigger signal.
You can use the same trigger signal to set a bunch of other pins to a 'default' condition at startup: rapid override, optional stop on, manual mode, etc.
