i laid the same floor last week in the local tile shop, had a job with the small tiles as there's meant to be 200 mm and 197mm tiles for the design i did but there were no 197's so i had to trim a few, they didn't look as good tho as there's quite a bevel on them.
I fixed the same thing recently - you need to trim the 200s most of the time, then I just use my pincers or grinder to rough the edges up to match the rest of the tile

Yeah I had to shave the tidlers down as well, same as above to match them in with the rest of the tiles.
