Yes but, yes but stolzy.
If his bike has ABS which only needs a thorough bleed and replace fluids, and otherwise it works, why ditch the ABS ? Just learn how to DIY the ABS bleed properly.
An ABS-equipped bike is much safer in an emergency than a non-ABS one.
Towards the end of the nineties, I had sequential non-ABS and ABS-equipped 1100S sporty machines. The later one gave me much greater confidence whilst thrashing around the wonderful granite-surfaced deserted roads in remote Scotland. You could go round a corner as fast as you liked, knowing you'd most likely be able to cut your speed rapidly in a straight-ish line if needed.
Only trouble was, those granite chippings up there tore the guts out of tyres; no wonder the bike-tyre specialist near Aviemore did a roaring trade all day long in the season.
