Is it possible to program an ESP32 TTGO LoRa32-OLED card using a serial port or an alternative to USB as it does not work?

Yes, all you need is to use Tx,Rx, GPIO0 & Reset.

Get yourself one of these and connect the wires to your board.

Or, if you have a simple USB to serial cable like one of these you can do it as well.

If using the later you only need 3 connections. Tx, Rx & Gnd, Hold RST & GPIO0 low, then release RST while keeping GPIO0 low, then release GPIO0. This will put it into programming mode. Then start your upload.
