Syntax error when trying to execute Python script to burn efuse on ESP32 board

Question

I own an ESP32 board (Lilygo TTGO T-Display). I'd like to burn the internal efuses that select the interval voltage so I always have a 3.3V regulator.

This is explained here: Note about GPIO12

I have downlaoded and installed everything.

When I run the command:

python3 components/esptool_py/esptool/espefuse.py set_flash_voltage 3.3V

I get:

components/esptool_py/esptool/espefuse.py: line 7: import: command not found
components/esptool_py/esptool/espefuse.py: line 8: import: command not found
components/esptool_py/esptool/espefuse.py: line 11: syntax error near unexpected token `subprocess.run'
components/esptool_py/esptool/espefuse.py: line 11: `    sys.exit(subprocess.run([sys.executable, '-m', 'espefuse'] + sys.argv[1:]).returncode)'

With this command :

python3 -m  espefuse set_flash_voltage 3.3V 

I get :

    sys.exit(subprocess.run([sys.executable, '-m', 'espefuse'] + sys.argv[1:]).returncode)

I have read the documentations three times, downloaded and installed everything needed.

What am I doing wrong?
