The modbus sensor does not have a value_template option to perform any calculations. So you will have to create template sensors from your modbus sensors. e.g.
template:
- sensor:
- name: My Modbus Sensor Divided by 100
state_class: measurement
device_class: temperature
unit_of_measurement: "°C"
state: "{{ states('sensor.my_modbus_sensor')|float(0) / 100 }}"
availability: "{{ has_value('sensor.my_modbus_sensor') }}"
