Use with ring buffer

Split with point from 20 to 30 meters from line

Result with ring buffer

Split line with points within 20 meters and 30 meters, the highlighted point is a little beyond 20 m

Linear buffer for point exclusion

Split line with points within 30 meters and distance between them greater than 10 meters

Result with linear buffer for point exclusion
