Hi @Aks 

There's no alternative to on-board ST-Link on STM32MP257F-DK. 

You might consider to get a STM32MP257F-EV board where JTAG signal are accessible on MIPI10 connector

For TSN maybe following link can help 

How to configure TSN switch - stm32mpu

How to configure TSN endpoint - stm32mpu

Hope it help

The J-Link "conversion" is provided by Segger - it's nothing to do with ST - so you would need to contact Segger about that:
