I've decided to abandon VEP entirely. We've been waiting 2,5 years, and quite frankly, I halved the processing overhead in Nuendo 12 after removing VEP.
I've been a VEP user since 2011, teaching it in universities and engaged in the community, but there's a limit to how long it's possible to wait. VSL is among the last to fix M1 compatibility, only passed by a couple of old-school plugin manufacturers like Lexicon, Musictribe and Kush Audio (which will probably never fix their plugins, their codebase is too old). I've abandoned those as well, and will recommend any students to do the same.
It was a pain rebuilding the template into disabled instrument tracks instead, but worth it. For remote usage of plugins and libraries, I'll look into Audiogridder instead in the future.
