Yes, you can, BUT . . . If it's "Tempered Glass" you cannot cut or drill holes in it after it has been tempered - it shatters. Anything that needs to be done to tempered glass is done BEFORE it is tempered. As for automotive safety glass (laminated), I wouldn't try to cut it with a grinder as you are liable to shatter one or both sides of the panel.
BTDT, I learned THE HARD WAY that you will be time & money ahead and with lots less aggravation to take your glass panels and the exact dimensions to a Glass Shop, where they have all of the tools & equipment, and most importantly the EXPERTISE to do the job properly.
