Is a non-WAAS Garmin 530 certified for an LNAV/VNAV approach? I may not understand all the details of what I'm asking but trying to wrap my head around it.

I am aware that before WAAS, some GPS aircraft were equipped to get vertical guidance by a Barocorrected altitude information sent to the FMS and along with the non-waas GPS could calculate (interpolate) glide path info and were approved to fly LNAV/VNAV approaches.

My question is whether the non-waas Garmin 530 has the ability and necessary FAA approval to perform this and if it is an option?
It seems if used on its own, the 5xx is not capable of LNAV/VNAV approaches.
