Not if the network blocks QUIC in its entirety to force clients to fallback to HTTP1. I'm pretty sure the network I'm currently on does this.

But, it looks like the type of fingerprinting in the article utilizes the fact that VPN connected devices are only connected to and sending data mostly to only one host, which using QUIC won't help with - you'd need to add some sort of "noisemaking" functionality involving sending bogus packets outside the tunnel, or possibly route VPN traffic across multiple nodes before forwarding to the actual vpn server ala Tor (as they propose in the conclusion).
