UPD:
TMC2208/2209/2225/2226 are slightly different from TMC5160

[gcode_macro HYBRID_TPWMTHRS]
gcode:
    {% set speed = params.SPEED|default(50)|int %} 
    {% set tmc_hz = 12000000 %}

    {% set x_rt = printer.configfile.settings.stepper_x.rotation_distance|float %}
    {% set y_rt = printer.configfile.settings.stepper_y.rotation_distance|float %} 
    {% set x_rs = printer.configfile.settings.stepper_x.full_steps_per_rotation|float %}
    {% set y_rs = printer.configfile.settings.stepper_y.full_steps_per_rotation|float %}

    # Comment/uncomment depends on default configuration for TMC, if you already enable tpwmthrs, for speed like 1mm/s you can leave it as is
    # Only for TMC22xx
    # SET_TMC_FIELD STEPPER=stepper_y FIELD=en_spreadCycle VALUE=0
    # SET_TMC_FIELD STEPPER=stepper_x FIELD=en_spreadCycle VALUE=0

    {% set x_tpwmthrs = (tmc_hz * x_rt/x_rs/256/speed)|int %}
    M118 X TPWMTHRS={x_tpwmthrs} ~ {speed} mm/s
    SET_TMC_FIELD FIELD=TPWMTHRS VALUE={x_tpwmthrs} STEPPER=stepper_x

    {% set y_tpwmthrs = (tmc_hz * y_rt/y_rs/256/speed)|int %}
    M118 X TPWMTHRS={y_tpwmthrs} ~ {speed} mm/s
    SET_TMC_FIELD FIELD=TPWMTHRS VALUE={y_tpwmthrs} STEPPER=stepper_y

And another 2 for enable/disable stealth/spread
