help: Increasing radar signature for small UAV

Yo

Is there a way how to increase rada signature to small UAVs?
I found some lines about increasing signature value but i am not sure how to add it or even if its possible.https://community.bistudio.com/wiki/A3_Targeting_config_reference#radarTargetSize

Or it would be nice to increase radar sensitivity to radar ground vehicles like Nyx (recon), so the vehicle would start to be usable
 

Those config values can only be tweaked thru mods, not scripts
