Hello, I am using the STM32U575RG microcontroller, and I am developing a board with a NEO-M8N model GPS, and I am using LPUART1. However, I am wanting to implement it with DMA. Could someone help me explain how to configure the microcontroller with DMA? I don't know where to start in configuring.

From GNSS, primarily receiving on the STM32 side

Perhaps look at
