Currently NOT, but in my plan.
If you choose GPT, that means you will only use it in UEFI mode.
Maybe you can try to install Ventoy manually.
1. create a Part1 and Part2 in the disk in GPT format
2. set Part2 as ESP partition and format it with FAT file system
3. In Ventoy's install package, there is a ventoy/ventoy.disk.img.xz file, xz decompress it to get ventoy.disk.img
This is a 32MB raw disk img. Get all the content in this img and copy them to Part2
Then you can try it.
