Meta Avatars dev with a Quest 2 and CV1

I'm playing around with meta avatars, and own a CV1 and a Quest 2. Is it possible to test multiple avatars in quest using a CV1 in windows unity preview mode for user A and a standalone build on quest 2 for user B? 

I'm using a Meta Avatars Template from Unity asset store - and when I try the above I get a functional avatar from the quest but not from the CV1. Is there a way I can do this? Would be preferable not to have to buy another oculus headset 🙂
