In my tests on a Windows host, after taking the command off, I find there is actually two right-side popups: One in the main Virtualbox window, and one in the VM window. Your commands get rid of the common error messages that may show in the VM window that used to show as bubbles at the top of the VM window but now show in the VM window's right-side notification bar. When these error messages are commanded to not show, the VM window's right-side notification bar in the VM window does not show.
However, the right-side notification in the main Virtualbox window does not disappear, whether the commands are in place or not. It shows the "Powering Up the VM" regardless of the commands.
I don't have a Linux host to test.
So by suppressing messages that may show in the VM window's right-side notification bar via the commands, the right-side notification bar in the VM window does not show. If any messages not suppressed want to show, the right-side bar in the VM window will probably come back.
But, at least depending on host, the right-side notification bar in the main Virtualbox window does not get suppressed by the commands. Clicking the [!] button does not hide the notification bar in the main Virtualbox window in a Windows host.
But like I said, it's a workaround, so we should wait for a native option from the developers. I can't guarantee the working of this solution in all scenarios unfortunately, I only tested it on personal windows 10 and linux as host.
