Share Nvidia GPU to DCV virtual sessions

If I am using console session, I am able to utilize Nvidia GPU but if I am using virtual session type I am not able to utilize the graphics. I suppose this is happening because the console session runs on DISPALY=:0 and virtual on DISPLAY=:1 and so on.

Is there a way we can share GPU among all virtual sessions? I am planning to use 5-10 virtual sessions.

I have tried this configuration but still no luck

[display/linux]
gl-displays = [':0.0',':0.1', '1.0','1.1']
