That question is going to require clarification to get an accurate answer.
If you are asking if TTL HSS will work with the rovelight the answer is yes to the extent that it works in H mode.
The TTL speedlite(s) have their exposure set by a pre-flash. The rovelight does not participate in that event so its contribution to exposure will be additive if both the TTL speedlite and the rovelight are striking the same subject in a way that is visible to the camera.
I've done what you're alluding to with other lights in H mode. It takes some planning and a bit of testing to get the light the way one wants it.
Oops forgot to quote the post I was replying to.

my Yongnuo yne3-rx receiver works with my Canon ST-E3-RT..
When using this setup does hss play well. I have another strobe I use with my yne3-rx and Yn-e3-rt but high speed sync doesn't work but that strobe also doesn't have a hyper sync option so was trying to utilize canons high speed sync. But with the rovelight having hyper sync option was wondering/hoping this combo plays well for hyper sync
