That's manipulation of the string held in var. Dollar sign and curly braces wrap the variable, the single percent sign say remove the shortest matching substring from the end of the variable contents, and the 'd*' is the substring to match, a lowercase d followed by any characters in this instance. var will still hold the entire original string, only the echo output is modified here. You can find more documentation here, https://tldp.org/LDP/abs/html/string-manipulation.html.

I don't think that addresses their issue with Ventoy, since this looks to just be a frontend over Ventoy. From the website you linked: "YUMI exFAT utilizes a bootloader based on Ventoy2Disk along with a custom YUMI theme and configuration enabling you to use advanced Ventoy boot methods with YUMI's helpful front end."

I am a big fan of Godot, but using Rust with Godot 4 through Gdextension is not in a very stable place yet, and I haven't been able to figure it out yet. Godot 3 with Rust Gdnative bindings was workable but a bit painful to set up.
