Not directly and the following isn't a hex editor but if it's intended purpose is to create "content" for LCDs then https://www.mikroe.com/glcd-font-creator might be what you're looking for.
Here's another one https://www.buydisplay.com/lcd-font-maker and another https://kapusta.cc/2020/03/20/fontedit/

I've not used any of them, I know Richard is using the one from MikroE.
