Possibility for disable signing Appx and continue signing Nsis

[egor-zalenski]

Target:
win: ["nsis", "appx"]

How I can disable signing for Appx package? Meanwhile continue signing a Nsis package
I have a certificate for windows and I set CSC_LINK and WIN_CSC_KEY_PASSWORD env variables.
Signing for .Nsis work well.
But I want to upload an Appx only for Windows Store.

Signtool are signing both packages and I can't upload a signed Appx package because of difference between "publisher" in the electron-builder.json and "publisher" in the Windows Store.

Without "publisher" inside electron-builder.json - signing isn't work
And I can't rename "publisher" in the Windows Store

I don't think that's possible. There's a sign arg for windows config that might pass you that information on what it's trying to sign, and whether you can skip it.
https://www.electron.build/configuration/win

sign String | (configuration: CustomWindowsSignTaskConfiguration) => Promise - The custom function (or path to file or module id) to sign Windows executable.

An alternative way I can think of is to write it programmatically such that you run a build for just nsis and then chain to the promise to build appx.
