STM32L4A6RGT7 Board setup

Hello together,
I am currently trying to start a project using platformio using the STM32L4A6RGT7 controller and I was not yet able to find any boards which would be compatible with this mcu. I then tried to look into the existing .svd files within the ststm32 platform and i was not able to find the correct svd file for my MCU, which is if i am not mistaken STM32L4A6.svd
Is this mcu not supported currently, or can I create a custom board and I am mistaken, that i cannot use any of the existing svd files?

I tried to build the project using an ioc file created with stmcubemx and the stm32pio plugin. The closest board i was able to find to my own mcu was the nucleo_l476rg, which uses a stm32l476rgt6. This leads to compiler errors:
Src/usb_otg.c: In function ‘HAL_PCD_MspInit’:
Src/usb_otg.c:79:38: error: ‘RCC_PLLP_DIV2’ undeclared (first use in this function); did you mean ‘RCC_PLLP_DIV7’?

*** [.pio/build/stm32l4A6rgt7/src/usb_otg.o] Error 1

I thought i could resolve it myself by creating a custom board, but I am wondering if it is possible without first finding it elsewhere.
Thank you in advance for any help

Greetings

Update:
It seems i was wrong. The svd file I was looking for is STM32L4A6x.svd

I created a working custom board file, so my problem is resolved…
