AM263P4: How to use the TI CMSIS library inside the MCU + SDK

Part Number: AM263P4

My project uses the mcu_plus_sdk libaray provided by TI,

But I also wish to utilize the functions from https://github.com/TexasInstruments/mcupsdk-cmsis/tree/main which are not present in the SDK. 

What is the recommended way to integrate these two SDKs?
