Carrier Board design for Verdin iMX8M Plus

Dear Team,
I am developing a custom carrier board for Verdin iMX8M Plus SOM.
I have a requirement of 4 ethernet port with TSN support. So I was planning to use Ethernet Switch.

Here My doubt is, in which pins of SOM, I can connect MDC, MDIO and INT pins of Ethernet PHY.

Please give a solution.

Thank You !
