Access SPI device in ULP

Hey guys,
Is there a way for me to access and modify the data in an SPI register?
My SPI device, a LoRa radio, reports back every few 10s of milliseconds, and I need to perform an action based on the result of the radio's operation.
After configuring the radio, the operations my esp32 performs are relatively simple, and the aim of the device is to be as low power as possible.
I would be grateful for any help, or tips.
Thanks.
