With a soldering iron and USB-CD PD trigger boards, I've successfully converted a few of this kind of thing.

There are barrel jack USB-C adaptors now that you can just glue in place. Very useful for homelabbers.

I love them, useful for super clean desk setups .

I use a 140w USBC charger -> USBC to Barrel Jack -> LG Ergo screen -> USBC -> Laptop. One AC plug powers the display & laptop.
