First of all, you can use the ST-LINK to program or delete with it, but not any Cortex-M based target. Only STM32 from STMicroelectronics are supported, not e.g. your TN2115 from FusensMicro.
But even if you want to program / delete an STM32 as a target, you can only use the ST-LINK for one target at a time, in this case either for the main STM32 on the NUCLEO, or for an external STM32. In the latter case you have to remove the double jumper (named ST-LINK, directly next to the crystal) on the ST-LINK so that the SWD connection to the main STM32 does not interfere with the one to the external STM32.
