enable z probe, printing

hello… my setup mostly a 3d print…
looking in enabling z probe for bed leveling using a proximity sensor…
want to make sure i uncomment the correct code in the rc7 firmware…or any that i should…
newb here learn as i go…hehe

// A Fix-Mounted Probe either doesn’t deploy or needs manual deployment.
// For example an inductive probe, or a setup that uses the nozzle to probe.
// An inductive probe must be deactivated to go below
// its trigger-point if hardware endstops are active.
//#define FIX_MOUNTED_PROBE (uncomment this)

this is already enable, use the z min pin for the proximity sensor?
// Enable Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN to use the Z_MIN_PIN for your Z_MIN_PROBE.
// The Z_MIN_PIN will then be used for both Z-homing and probing.
#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN (already uncomment)

enable this…
Bed Auto Leveling
// @section bedlevel

//#define AUTO_BED_LEVELING_FEATURE // Delete the comment to enable (remove // at the start of the line) (uncomment this)

// - Prevent Z homing when the Z probe is outside bed area.
//#define Z_SAFE_HOMING (uncomment this)

thanks…
