Can Canon RT wireless flash do off-camera second-curtain sync?

I want to use second-curtain sync with Canon’s native wireless radio flash system for off-camera flash. Older information says Canon RT did not support this wirelessly, but I’m looking for a definitive current answer. I currently use 430EX II flashes with Yongnuo triggers, which works but is cumbersome. Does Canon’s own RT system support off-camera rear/second-curtain sync, and if so, what hardware or camera limitations apply?

Canon RT flashes and RT triggers will not do what you want. There are 3rd party RT triggers and flashes that will.
The Yongnuo YN600EX-RT and YN-E3-RT, for instance. Unlike your Canon 430EX II flashes, the YN600EX-RT and several other third party flashes have RT receivers built in, so you could eliminate the need for external trigger receivers and the accompanying batteries for each of your flashes.
Since this answer was originally written, I've also used the Flashpoint R2 Pro Mark II (rebranded Godox radio transmitter) and Godox X1R-C receivers to use second curtain sync with my 430EX II.
I've also dumped all of my Yongnuo flashes and replaced them with Flashpoint/Godox products. In my experience the Godox stuff has been very reliable, unlike the Yongnuo flashes.

Yes—but only on newer Canon RT transmitters and compatible camera bodies. Older Canon RT gear did not support wireless second-curtain sync; Canon even confirmed that the 430EX III-RT did not offer second-curtain sync during wireless flash shooting.
As of February 2021, Canon added this capability with the ST-E3-RT version 2 transmitter (or updated v1 units serviced by Canon in some regions). With that transmitter, off-camera second-curtain sync works with Canon RT-capable Speedlites, but only on 2020-or-later camera bodies such as the EOS-1D X Mark III, R5, R6, M50 Mark II, and later models. On newer cameras with the multi-function shoe, the ST-E10 also supports it.
If you’re using older Canon bodies, Canon’s native RT system still won’t give you wireless second-curtain sync. In that case, third-party systems such as Yongnuo RT-compatible gear or Godox/Flashpoint triggers and receivers have been used successfully for this feature.
