Not sure what pre-biased ideas you are carrying into this question. Sure, some (IMHO unqualified) theories say run NDI and Dante on dedicated LANs - hard all that before, too:

With a capable healthy AV network, and proper QoS configurations vMix, NDI, Dante, and OMT can co-exist.

Full HD production site here on vMIX Max subscription, NDI-HB and NDI-HX3 inputs (upscaled to NDI-HB using the NDI Bridge). For historical reasons on the site, we operate an dedicated additional Dante network side by side.

Sure, all that requires a very powerful PC, an extreme powerful GPU (A4000 here).

Due to some new invented issues in Windows 11 25H2 updates (sigh!), our Thunderbolt 4 stopped to be workable (as TB, ok for USB et al) for few inputs (BMD UltraStudio 3G) and an output (BMD UltraStudio HD Mini) because inop. As a workaround for the output, we temporarily operate an OMT output to a PC running the nice Windows 64 bit build of the OMT decoder, driving a HDMI port as an ad-hoc workaround. Creativity is key 8-). Needless to say on the same VLAN.

OMT allows - by design - to be operated on an unmanaged GbE network, at least up to FullHD@50 (likely @60 too).
