How do I disable the safety switch on Pixhawk 6X?

[StenPetrov]

I'm trying to test a new ESC. I have a Pixhawk 6X sitting on my desk, along with an ESC, a motor and a battery, trying to test the motors.
On the motor test screen, QGC INSISTS on some safety switch, even though I disabled all the prearm checks.
Is there any interface to disable the switch? It's not one of the "Arming checks" and there isn't a specific user control for it.
The docs are useless, only saying "if it's PX4 you have a switch" - I don't have a switch, just the minimum number of components.

Is it saying that message where it goes "Hardware safety switch!"?

It shows it on the motor test screen
