Transparent trailer - can this be added on?

I tried to get the "transparent trailer" mirror/camera on my Yukon, but apparently chip shortage made it unavailable for my build level. I see GM has the add on camera available now, but with the following caveat: "This add-on camera enables a Transparent Trailer View on select models with Enhanced Trailer View Package (RPO ZM1)." I don't have the RPO ZM1 package. Is there any way to get a trailer camera that will integrate with either the mirror or the infotainment system?
