It"s impossible to create ISO for Office LTSC (VL) such like ISO for Office Retail.

If you need offline installation package for Office 2024 Pro Plus LTSC pt-pt, it"s possible to create and convert to ISO but for installation process to start you will need some script like Office(R)Tool or something... Or OInstall by Ratiborus (easiest option) but to use it you will need to turn off your AV...

No ISO for any Office LTSC edition, installation via ODT.
