Need to stop office apps from EVER opening in a browser on my PC. Was told to post here by answers.microsoft

Question

I need to stop files (Excel files on SharePoint/OneDrive primarily) from opening in a browser on my PC. I feel like I've tried everything. All the advice I get is to click on the ellipses and select "open in desktop app", or go to SharePoint and set the advanced open settings to "open in the client application". Neither of these work in my situation. (I can explain why if you need that info, but it is uninteresting). I need my computer to never open a file in a browser, even if I forget to click the ellipses and specify how to open. Or maybe I don't realize I'm looking at a SharePoint library instead of file explorer because I'm in a hurry. Whatever the reason, I need office files to open in their desktop apps no matter what. If that can't be done for some reason, an error message would be fine. Even BSOD would be preferable to opening the file in a browser. Just anything I can do (hopefully not destructive, like gimping the browser install) to make it so my PC simply cannot open a file in a browser. Sorry for being long-winded, I've just asked the question to several people so I'm trying to preempt some of the suggestions that I've already received. The advice I got from answers.microsoft.com was to post here:
Moreover, if your requirement is to prevent any type of the file to open in the browser irrespective of it storage location on your computer, I would like to suggest you cross-post your concern in the Ask a question - Microsoft Q&A with Office & Windows tag to get the detailed help from experts.

Thanks!

This is awful! Microsoft, can you please respond as this is frustrating to our company and all our customers! Make this an easy option for your customers to open in the Desktop Apps - NOT THE BROWSER!
