Beats Flex connection pop-up

How to prevent beats flex from trying to connect to every apple device?

When I turn on by Beats Flex, the connection pop-up window shows on every apple device near me, even not my devices with different Apple IDs.

How to make it connect only to my devices? And stop showing connection pop-ups to other Apple devices?

It is problem when I am in some public place where a lot of people, and each of them got a pop-up alert with questions about connection to my Beats Flex.

I already tried to re-pair and reset my Beats Flex, but it doesn't help.

Firmware version of Beats Flex: 3.7.2
