How to make a 301 redirect from all child pages to the parent?

Question

URL Handling

Good afternoon. There are pages on the site (CMS Joomla):

https://www.genakom.ru/contacts
https://www.genakom.ru/o-kompanii
https://www.genakom.ru/rasprodaja

etc.
When publishing articles, CMS creates ( https://www.genakom.ru/newsour/8-newsshop/216-post...) duplicates with the above url:

https://www.genakom.ru/contacts/newsour/8-newsshop/216-postavki
https://www.genakom.ru/o-kompanii/newsour/8-newsshop/216-postavki
https://www.genakom.ru/rasprodaja/newsour/8-newsshop/216-postavki

You need to make a 301 redirect (preferably through .htaccess) of all child pages of any nesting:

https://www.genakom.ru/contacts/newsour/8-newsshop/216-postavki/newsour
https://www.genakom.ru/contacts/newsour/11-newsshop/216-postavki
https://www.genakom.ru/contacts/newsour/8-newsshop/216-postavki/216

To the parent:
https://www.genakom.ru/contacts/
I ask for help with writing the conditions. Thanks in advance
