I have no doubt that the M1 EP will work great for 10k OCI. I doubt Hyundai feels the same way. Follow the maintenance guide until the powertrain warranty runs out.
In my opinion, Hyundai is too conservative with their OCIs. My old 2010 Tucson required 3750 miles / 6000 km OCI, which is nuts for today's modern oils.
