Homeassitant core : how to create a template helper?

Configuration
1

i have no access to config.yaml to create template sensors.

i want to use my codes , but how i can enter them into a helper ?

eg.

{%  if states("input_boolean.merker5")   == 'on' %}
  +aanvt
  {%- else -%}
  -uitvt
{%- endif %}

my available helpers in HA_core

how can i find a walkaround to make my custom helpers/sensors ?

thx in advance

its HA core , i cant install addons , and also its a homeassistant server made by a 3th party .
so updates/upgrades are controlled by the 3th party ( a manufacture of domotics)

The version number is displayed in Settings > About.

The most current version is 2024.2.5. What is your version number?

You should contact whoever is managing your Home Assistant server.
