Yes, your solution is the only one possible currently in QGIS. See also here:

QGIS is presuming that PBF vector tiles are always served in CRS EPSG:3857. 
Which is correct for, wild assumption, 99 % of vector tiles available. The 
Mapbox standard is also not mentioning a CRS anywhere:

If you can't live with above solution, you can try to convert the vector tiles 
into a different vector format as outlined here:

I haven't tried that yet, as the solution outlined by Richard Greenwood works 
for me.
