search in the settings for 5g click a result from the "other" category in the search results! then u can find those hidden options! it is a bug, that they do not show up in the data usage if u navigate there normally i hope they will repair it soon
Dial *#*#3642623344#*#*. Go to Settings -> Network & internet -> Internet -> SIM1. It should be there now. Of course, your network needs to be supported first though.
