Seeking smaller interior knobs (993)

[narkotic]

Hi - I've recently installed a new carplay capable radio (not the porsche one) that has a display larger than the opening therefore it rests outside of the dash a bit. This caused me to have to temporarily remove the 3 knobs above it (fog light / cig lighter, etc) while I seek out smaller versions. Does a such thing exist? I've found a few replacements online made of metal that look killer but they all seem to measure larger in diameter, not smaller. The stock ones are about 29mm in size, i need something closer to 25. Any ideas / suggestions? I've thought about finding a decent looking bolt (allen key) to use for two of them just to fill in the hole for now and for the lighter I can probably find some sort of generic plug or USB charging plug instead...
