Is Insider program MS account dependent or device dependent?

[Abinav_Shankar]

I am running windows insider build through the insider program. I'll be purchasing a new laptop tomorrow which is for my primary use. I will be using the same Microsoft account in it but I don't want to install insider builds there. But I still want to check out insider features on my old PC. Is it possible to leave out a device from insider builds even while using the same MS account?
