AM263P4: MCU-PLUS-SDK-AM263PX: Changing the MCSPI Master Driving Power Settings

Part Number: AM263P4
Other Parts Discussed in Thread: TMDSCNCD263P

Hello.
I'm currently using mcspi for master/slave communication between two boards. During the project, I encountered an issue requiring me to increase the driving power (the output of the transmitting side) of the master board. Is there a way to increase this driving power? If so, what part of the CCS do I need to change? Do I need to add code, or do I need to configure it in syscfg?
Or is it possible to change the driving power of the am263px? If not, what is the default setting, and if so, can I change it?
I'm currently using the am263px-cc board (TMDSCNCD263P) and the SDK I'm using is mcu_plus_sdk_am263px_11_00_00_19.
The example I'm using is mcspi_loopback_interrupt_lld.
