Changing compiler version in haskell project

I am in the process of setting up a build to generate aarch64 binaries for the neuron package.
The goal is to add a bundle just as is done with the linux-bundle.

Right now there is an issue related to the regular ghc version used and I want to circumvent this issue using a ghc version possibly working (I already built cachix using ghc883 so that could be a candidate).

Now I’m stuck changing the compiler used in neuron.

Can somebody help me with this ?
