TMS320F28379D: Interrupt priorities for ADC completion interrupt and external GPIO interrupt. (Interrupt Preemption)

Tool/software:

I am using F28379D DSP for a power electronics project. I plan to use all the 4 ADCs for Analog signal conversion. I want to trigger them through software and the forceMultipleSoC API will be called when there is an external interrupt from a GPIO (XINT1). I wanted to know if the ADC conversion completion interrupt can preempt the external GPIO interrupt? I know that the ADCs can be directly triggered through the interrupt, but in my current application, I want the trigger control in the software through an external interrupt ISR
