SimObjects variables

Reading and setting A-Vars of the user aircraft through simconnect has always been possible, but how about variables on simobject that have been instantiated by the silconnect App, is there a way to control their “L-vars” (Local variables)? {Avars are still accessible through simconnect}
SimObjects instantiated by the simconnect client might have a Model file that includes some visibility or animation codes based on their “Lvars” (Local variables), is there a way to Read / Set those Lvars ?
The Internet said “NO”, that’s what I have been reading so far, but can Microsoft & Asobo make this available through simconnect clients ? As this might open some closed doors that we originally had open with older sims like P3D and Xplane
