Additional unversial exe package is generated

[qishibo]

• Electron-Builder Version: 23.0.2

• Node Version: v16.20.0

• Electron Version:12.2.3
• Electron Type (current, beta, nightly):

• Target: {"target": "nsis", "arch": ["x64", "arm64"]}

if I build arm64 and x64 nsis target, and my build field like bellow

"win": {
  "target": [
    {"target": "nsis", "arch": ["x64", "arm64"]}
  ]
},
"nsis": {
  "artifactName": "${productName}-Setup-${version}-${arch}.${ext}",
}

after building I got 3 exes instead of 2(arm64 and x64), it seems that an universial package is generated, and its size is about 2 times bigger than arm64 and x64. I am quite confused about this, can I remove the universal version??

tried again in local machine, if I don't want this universal version, how can I config to reduct this

I took a solid look at the code and am unable to determine the reason as to why a universal package needs to be generated. The logic is quite complex though and AFAICT I don't think it's possible to remove the universal package from being generated.
AFAICT, the logic exists here:

electron-builder/packages/app-builder-lib/src/targets/nsis/NsisTarget.ts

Lines 237 to 252 in f941f18

	await BluebirdPromise.map(archs.keys(), async arch => {
	const { fileInfo, unpackedSize } = await this.packageHelper.packArch(arch, this)
	const file = fileInfo.path
	const defineKey = arch === Arch.x64 ? "APP_64" : arch === Arch.arm64 ? "APP_ARM64" : "APP_32"
	defines[defineKey] = file
	// eslint-disable-next-line @typescript-eslint/no-unnecessary-type-assertion
	const defineNameKey = `${defineKey}_NAME` as "APP_64_NAME" | "APP_ARM64_NAME" | "APP_32_NAME"
	defines[defineNameKey] = path.basename(file)

	defines[defineHashKey] = Buffer.from(fileInfo.sha512, "base64").toString("hex").toUpperCase()
	// NSIS accepts size in KiloBytes and supports only whole numbers

Looks like there's been a request to disable the universal package before as well: #8298

Would anyone be willing to test out this patch-package?
