Not sure I have entirely understood the issue but here's a try anyways :)

I would add a build option to the host qt6 for network support in 
Kconfig, then have your remote objects package depends on this option 
being selected. If it's not selected, your package won't be selected 
either, which is what is desired I think?

Cheers,
