Running any language on Duo (64MB)

Hi,

I ordered a Milk V Duo board and I’m trying to come up with the best way to program for it.
In my project I don’t really need Linux and would like to use it more as a generic SBC and seeing that there’s Arduino support gave me hope.
But I don’t really want to write Arduino code, so I was wondering if there’s a way to compile a binary in an other language like Rust and upload that to the board?

Also is it possible to use the Linux core for other tasks?

Thanks.
