Any way to limit GPU RAM usage with aerender?

I'm trying to get multiple aerender.exe instances working like it did a few versions ago when you could disable GPU rendering.  The problem seems to be that now I can't disable GPU rendering and each instance is using a ton of GPU memory, so I can only run a couple threads at a time, maybe three if I'm lucky.  I used to regularly run ~10 with no issues back when I could disable GPU rendering.

 

So... since I can't disable GPU rendering, is there any way to limit GPU RAM usage so I can again run a bunch of threads?

I would recommend you set GPU by Device manager or use the command line like "-mfr mfr_flag max_cpu_percent".  The link below would be helpful.
