No, unfortunately it happens every time the light is turned on.

Or jumpstart when you turn on the light on a low mode? Or something else?
Something else: it’s similar to the jumpstart at turn-on that Anduril explicitly does when compiled for some lights, but when compiled for the D3AA it does not have that enabled. Despite that, the driver does it on its own.
Conclusion after a discussion in a GitHub issue was that it was a hardware limitation of the D3AA: Flash in lockout mode with '1h' or '2h' and a low light setting · Issue #83 · ToyKeeper/anduril · GitHub
