If you have a Television with HDMI in, you can temporarily hook the RPi 4b up to the TV.
Then you would need a HDMI to micro HDMI converter cable and a usb keyboard.
If you don’t have a usb keyboard, you could maybe borrow one from a friend for a day.
Then the only hardware you would need would be the HDMI to micro HDMI cable.
