AVR on L2 without Primary L1 and latest stamp

I recently switched to L2 fromH1b. I do have an expired L2 stamp which I used 6 yrs back before H1. Can I use my new I94 and L2 status to return to US on AVR after a 21 day Canada visit by air… automatic visa revalidation?

I happen to have a Candian PR for enteeing into Canada

The downside is… the primary L1 visa holder will not be travelling with me
