Siren always ON boot time 5 seconds - firmware - Relay

Good morning, can you help me what's going on with my nodemcu and firmware?

When I power off/power on the Esp8266 board the relay is always ON during the boot time (+/- 5 seconds). When the firmware starts and it goes back to the OFF state.

I am using the firmware and I want to use the relay for a siren switch.

So I can't get the siren ON (5 seconds) before the firmware loads.

Anyone with this problem and how to solve it?

I attached a video explaining better my issue (

Firmware: 2.2.6
