It is a pain to open avast browser then change to private mode on a new window and start my browsing. Can the browser be STARTED in private mode (a command line switch, perhaps?) If not, consider it as a suggestion for a simple improvement 
tnx.
If someone here in the forum can put the link to everyone put us suggestions and improvements for Avast products I will be grateful. 8)
On one of the last couple of program updates, I think the 23.11 update, they added the option to leave feedback but that’s only on an uninstall.
This is a shame, it would be good somewhere in the forum or on the antivirus itself.
Anyway, I think someone here should know where we can put a memories in the Avast team to read and implement.
Some time ago I put a comment saying that Avast should modify that bar that stirring one side and the other time when you put to update the database, I think that bar very ugly. It should be done equal to ESET NOD32 and a beautiful bar showing the percentage and amount of MB that is being made.
I believe this is the place to put the news you want Avast to have to be improvements or resources and change in the Avast interface.

Note that there is a forum specifically for the Secure Browser.
Avast WEBforum - Consumer Products - Avast Secure Browser
If my italicising, the part in your Quoted text:
I would have though it best to post this in the Avast Secure Browser (ASB) sub-forum - https://forum.avast.com/index.php?board=78.0 - If for windows this sub-forum https://forum.avast.com/index.php?board=122.0
There may even be something there.

Scroll down to @Adjust Privacy Guard’ and see if that helps.
I don’t use the ASB product so I can’t speak from personal experience.
