There are a number of different options, so this may be guess that misses!
But it sounds like you are speaking of what some call "wheel simulators"?
A thin cover that might look like a big broad hub cap?
If that is not too far off the mark, try looki9ng for two of the simulated lug nuts. They may actually be just thin covers and not actually hold the wheel on!
Looking closer, you may spot those two in different ways:
!. If you gently tap each lug nut cover, there may be two which sound different?
Something like ding, ding and then click?
2. There may be two which look a bit different right at the point where their base meets the rest of the sim. Some have a circle laying on the larger metal and some have no circle?
3. There may be points built into the nut covers that may look like a - pressed into one side of the fake covers!

Different brands may have different features to look for to ID the ones which can then unscrew to release things!
What I am thinking is that finding the fake two, unscrew them and that let the big fake cover come off and THEN you see real lug nuts if you wanted to remove the wheel!
There are tools to get them off but I find channel locks are good enough as long as I pad them to avoid marking the soft, thin metal!
If they are hard to get off like REAL lug nuts, my guess may be wrong, so go with that in mind!
