Can you syskey scammers when they use support.me

I was trying to do a syskey on a scammer, but realized that unlike teamviewer, I am unable to access their computer any way. Is there anything else that I can do in order to troll them/waster their time. Also, is there any way to mask that I’m using a virtual machine because everytime so far they just run sysinfo and can see that it is a VM.
