As i remember, on diagnostic tool there are special function INPA/DISA, after for example fluid replacement to circulate the brake fluid by ABS unit. But from practice, yes, you can bleed from caliper, some notes, don't open fluid reservoir before you finish change the lines, need for ABS unit not to "swallow" air in. And just after you can open reservoir, fill it /refill it, and open calipers, from the longest line side, as usual.
