Question How to remove viewed/read and other no used parts?

Hello dear developers!
How can I remove or disable these parts of my Kunena 6 Forum (I showed them in the attachment)

1. Read/Viewed
2. Gender
3. Birthday
4. Category Icons column
Thank you
 

Have you ever been View on the Kunena Forum: Configuration
Did you check the tab extra to see if there is anything you can do?
or on the other tabs?
Or else the user has to access his Forum account at the front
Profile Edit.
Or are you looking for some kind of CSS persuasion to hide this info?

Thank you
I analized every page in Kunena configuration, searched Kunena Forum before asking question here, but I could not find answer.
Here is my Extra page as you mentioned (in the attachment).
No place to disable viewed or read or gender or birthday.

well I don't see where all this can be diabled
And that of user info I think that the user himself can remove it via the front when he is logged in

I cannot ask every user to edit their profile.
I want automatically remove gender, birthday information form the frontend view.

How can I do it from the backend?

I think that this should be done via the database with a special sql command,
but I don't know which sql command.
maybe a kunena developer can post that here
