Simbrief and ILS or RNAV approaches

I was just going ask how Simbeirf distinguishes between VFR and IFR. There doesn’t seem to be a place to set either one as you can in the World Map. I don’t fly airliners, only GA, and mostly the TBM. I think might have to do with the plane type you use in Simbeirf whether you get VFR or IFR, but not sure of that. Just tried amping up the speed in the plane profile, it didn’t change a thing.

I do my lateral planning outside of Simbreif and then paste the route into the route box.

I assume you mean the Rout Box in Simbrief, is that correct?

Thanks for the response.
