Hello,
Unfortunately that's not possible if you have Microsoft 365. It comes as a package. You would have to uninstall the entire Microsoft 365, and reinstall using the instruction below:
Please go to https://www.office.com
Sign into the Microsoft account you used for the subscription. Click on Apps on the left.
Then on the upper right, click on "Install apps". This will now download the installer file. Once downloaded, click on the file to install. It will install the Desktop version of the apps for you then.
