Is there a BeagleBone-AI defconfig included in U-Boot?

Hello! I’m studying u-boot.
Currently, I’m trying to boot the Linux kernel using U-Boot on a BeagleBone-AI board.
However, the only defined defconfig in U-Boot is for the BeagleBone AI64.
Is it not possible to use U-Boot with the AM5729 BeagleBone AI?
I’m new to this field, so my question might be naive. Please forgive any ignorance.

Thanks for your helps!!

On mainline u-boot, use am57xx_evm_defconfig
