Here’s how to get past that in Chrome, Edge, or other Chromimum browsers. I did this from Edge Chromium:
First, when you go to download the file, you’re going to get the following warning. Click the “…” button and select Keep as shown.

Next, the Downloads manager page will open up, and you’ll see this second warning. Click where it says “Show more” which will then change to “Show less” (as shown) and click “Keep anyway”

Finally, click the “Show in Folder” to open Windows Explorer to your download location. When you double-click on the downloaded installer, SmartScreen will pop up this final warning. Click “More” and you’ll have the “Run anyway” button revealed. This will mark the executable as safe and you should see no further prompts for this file on this system.
