I don't have a USB-C network card! How can I try to install another OS if I cannot boot from external media, please explain?

Start Internet Recovery pressing Option + Command + R.
It will install latest macOS supported by your machine.

When using opshin+command+r, it prompts me to install the latest version of the OS, which took more than 7 hours to install, but the error remains the same (

Start in diagnostic mode and see if any hardware error is reported.
You should get an USB-C combo hub with LAN connector from Amazon.

If you erase the Mac, Startup Security Settings still asks you for administrator?

Scroll down to new installation options.

MacBook after DFU restoration! there are no accounts or anything! but on all MacBooks, if it is clean and there are no accounts, installation from external media is prohibited by default! I ordered a network card for USB-C! I hope this helps since all the tips from the above article do not change anything! Right now I’m trying to restore via the cellular network, maybe something will help until the network card arrives! I also erased a couple of MacBooks in the office to check the Wi-Fi network, they were restored without problems via Wi-Fi!
