Look at the inside of the disc rota - toward the axel, and if you see a spindle that looks like a 'railway track' it probably has ABS No difference in bleeding the fluid
Trace the fluid line(s) coming out of the master cylinder. If they go directly down to the front calipers, no ABS. Looking for a toothed rotor on the wheel won't confirm it; bikes like RSV4s have had a rotor front and back since 2011 for the aPRC electronics, but ABS was added only recently. Bleeding is the same as on a non-ABS bike but more difficult since the pipe runs are longer. There is a post on elsewhere on here about how hard it is to bleed the brakes on a Multistrada with ABS, and a potential solution.
