Turn on switch without calling triggers (on_turn_on, on_turn_off)

Hi! I’m trying to configure switch (id_relay) that will be turned off automatically after few seconds. Exact time depends on relay will be turned on via service (then after period specified by duration variable) or manually (then after period specified by g_overtime_default). Below is simplified configuration, but rest is not important now. It works fine for manual on (changing state of id_relay from HA), but unfortunately after calling service turn_on, the on_turn_on trigger is called and switch is turned off after g_overtime_default period. Is it possible to call id(id_relay).turn_on without executing on_turn_on trigger? Or any workaround?

globals:
  - id: g_overtime_default
    type: int
    restore_value: yes
    initial_value: '10'
  - id: g_overtime_current
    type: int
    restore_value: no
    initial_value: '0'

api:
  services:
    - service: turn_on
      variables:
        overtime: int
      then:
        - lambda: |-
            id(g_overtime_current) = overtime;
            id(id_relay).turn_on;
    - service: turn_off
      then:
        - lambda: |-
            id(g_overtime_current) = 0;
            id(id_relay).turn_off;

switch:
  - id: id_relay
    name: id_relay
    platform: gpio
    pin: GPIO12
    on_turn_on: 
      then:
        - lambda: |-
            id(g_overtime_current) = id(g_overtime_default);
    on_turn_off: 
      then:
        - lambda: |-
            id(g_overtime_current) = 0;
