UART RS485 3.5 inch panel DLC35010R

I'm trying to figure out if RS485 will work on my 3.5 inch DLC35010R display panel directly to UART. In the ESP32-S3 datasheet it shows that I can enable RS485 full or half duplex. The pinout for the four pins on uart on my panel say 5 volt, Gnd, tx and rx. I'm fairly sure I'm not going to see full duplex, because of the 5 and 0 volt rail. Hoping for half duplex at this point. The datasheets/diagrams do not show where the TX/RX lines go for uart. The UART example on elecrow's website for this panel keeps asking for <SoftwareSerial.h>. Which is meant to be built in. And I tried a few libraries, but nothing worked. Everything else thus far works great though.
