I don't think .NET has virtual threads (async/await doesn't count), and it definitely doesn't have anything similar to ZGC/Shenandoah — two garbage collectors that provide sub-millisecond pauses with heaps up to the multiple terabyte range. You can also go completely pause-less on commercial JVMs from Azul.

The .NET GC philosophy, so to speak, is to provide such guarantees by allowing programs to avoid GC entirely with value types.

Eventually, Project Valhalla will provide this on JVM-land, but it doesn't seem like the day will soon come.
