I'd like to live better with Global Values

Oh. Yeah you can’t do that. But I think you could accomplish the same thing like this:

[tmc2209 stepper_x]
uart_pin: PC4
run_current: 0.8
hold_current: 0.6  
sense_resistor: 0.110
stealthchop_threshold: 999999
driver_SGTHRS: 60   
diag_pin: PG6

[gcode_macro GLOBAL] 
variable_xy_home_current:0.7
gcode:
    {% set global = printer["gcode_macro GLOBAL"] %}

[gcode_macro _HOME_X]
gcode:
    {% set home_current = printer["gcode_macro GLOBAL"].xy_home_current %}
    {% set run_current = printer.configfile.settings['tmc2209 stepper_x'].run_current %}
    SET_TMC_CURRENT STEPPER=stepper_x CURRENT={home_current}
    SET_TMC_CURRENT STEPPER=stepper_y CURRENT={home_current}

    G4 P500

    G28 X

    G91
    G1 X-120 F1200

    SET_TMC_CURRENT STEPPER=stepper_x CURRENT={run_current}
    SET_TMC_CURRENT STEPPER=stepper_y CURRENT={run_current}

#### _HOME_Y same except for "G28 Y" and "G1 Y110 F1200"
