I think that the simplest way for you would be to download the older Armbian image with the older u-boot version, USB-boot it and then use the two dd commands to install u-boot on you actual boot device.

u-boot from Armbian_23.02.0-trunk_Bananapim5_sid_edge_6.2.0-rc3_minimal.img hangs if I try to boot with my USB hard disk connected. I replaced it with u-boot from Armbian_22.08.7_Bananapim5_bullseye_edge_5.19.16.img and that one works fine.
