For heating regulation I use timers in the thermostats. Sometimes I have to deactivate the timers for one or for all thermostats or activate them. I‘m using a lua scrpt with the hardcoded timer-ids. Would it be possible to insert a switch in the thermostat device to activate or deactivate all timers for this device. It also should be possible to change this switch via script.

You are aware of timer plans? https://www.domoticz.com/wiki/Timer_Plan
This at least will give you the opportunity to switch to another timer schedule for all devices eg holiday schedule or away schedule.
