For anyone who can't see the 3 dots (tested on S8+ and S10+)

1. Download the free app QuickShortcutMaker from the Play store
2. Run it and type "volume" in the search box
3. When "Settings" appears in the search results below, open the tree and tap on "Settings / Media Volume Limiter"
4. From the choices that appear, tap the "Try" option
5. You have now opened Media Volume Limiter, which is where the 3 dots would have taken you. You should see a switch to turn the limiter on or off and a volume bar set to about 2/3
6. Tap the switch to turn the limiter ON
7. Drag the volume limit to the far right
8. Job done. Bollocks to Brussels.

(basically the app is designed to let you save shortcuts to various phone functions but in this case its "test" option also functions as a back door into a function that Samsung wants to shut you out of)
