Damage to clutch at “Motorbrake” without idle in between?

Hello. Can I damage the clutch if, for example, I roll down the mountain in the 3rd course and only with the clutch “brake”, but in the meantime I don’t uncouple (so don’t roll in between in idle mode)? So, as I said in my example, always leave the gear in it and only with the clutch “brake”! Thank you!
