The project lists several DIY options for building (more like buying and plugging in) the hardware yourself. You might be able to find an off-the-shelf VGA-to-HDMI adapter/converter that would then be downstream compatible with the rest of the stack. There is discussion about VGA support in the project's GitHub Issues and Discord.
