Lilygo-T-Relay S3 - Relays triggering on boot

Hardware
1

Apologies if this is better off in the hardware section. I was hoping to find a software solution to the problem.

So I’ve got a Lilygo-T-Relay S3. All the relays trigger for about 100ms on boot. I vaguely remember hearing that most of the GPIO pins going high on boot is standard behavior on ESP’s.

I’m pretty sure these relays are controlled over SPI through a shift register so it doesn’t really make sense to me why the relays would go high on boot.

Is there any way to stop this behavior for all the relays? If unavoidable I would at least like to have the relay controlling my garage door on a pin that maybe doesn’t exhibit this behavior?

Thanks heaps

edit: There seems to be discussion of this behavior here:

This guy thinks he’s solved it:

My question is, what’s
mode: OUTPUT
and how could that stop the relays triggering at boot?

I’m planning on acquiring this device,
but when I try to build the default config

esphome gives an error on the output component.
I can just remove that one, but I’m wondering if this won’t break anything?
may I ask what your config looks like

and of course also if mode: OUTPUT fixes your issue. because having that specific issue won’t be pretty in my situation
