If the memory spec and chosen pinouts match existing discovery board, it might be possible to flash the memory with the programmer. Otherwise, you might have to flash the mcu with an app enabling you to program the flash indirectly, and finally program the stm32 witg its final user code.

What board? What chip?

The NOR parts surely have data sheets or manuals.

Several EVAL and DISCO series boards have support for NOR memories within the BSP section of the HAL examples.

The ST-LINK provides a means to add external loaders to flash memories attached to a board.

Consider also engaging staff with specific experience/competence in the technology involved.
