Disable HTTP/3 QUIC Forcibly with URLSession

Is there any way to forcibly disable using QUIC? I've noticed this ends up causing issues with our ISP / router, and noticed for many of our customers as well.

Creating an ephemeral session doesn't change things, and setting the request to "assumeHttp3Capable" to false doesn't fix things either.

We are using Cloudflare Workers as the URL we are hitting, and thus aren't able to disable this server-side.

Can anyone respond? This is pretty basic functionality
