When grinding stuff away I have always taken it off the stand it self, just mark out the place where the stand and the stop meet and do a little at a time.
The reason for doing the stand is if you ever want to go back again it is easy to remove the stand, then walk into a welding shop the get some material added back on or you can buy another stand quite easily or do a swap with another member here.
When the bike is lowered grinding off the stop will not work for everybody, "it will for some but not for all", it will help the bike sit better when on the stand but getting it onto the stand can be a problem, because the stand is still full length but the bike is lower you may have to lean the bike way over to the right to get the stand into position before leaning it to the left and onto the stand.

Ridding a motorcycle keeps things in balance.
