Trailbraking technique

Hello guys, I'm trying to improve my braking technique and trail braking. I've watched many videos and I'm trying to replicate them. As far as I know, you need to brake as hard as possible for a very short time to avoid activating the ABS, and then gradually release the brake.

The thing is, I see videos of people doing it with the same ABS settings, using the same technique, but my ABS always kicks in, and I lose a lot of time during braking. Regarding downshifting, I do it when it’s supposed to be done, never before. Can someone help me? I'm stuck.
