Ok, I got it booting, so I did:
 
set devtype nvme set devnum 0 set distro_bootpart 0 set prefix /boot/ load nvme 0:0 $loadaddr /boot/boot.scr source  
Doing a printenv before I see:
=> printenv arch=arm baudrate=1500000 board=evb_rk3568 board_name=evb_r_targets=mmc1 mmc0 nvme scsi usb pxe dhcp spi bootcmd=bootflow scan -lb bootdelay=1 bootp_arcNDI:003000 cpu=armv8 cpuid#=54434e4b383000000000000000070d19 dnsip=192.168.1.253 eth1addr=1e000 ethaddr=1e:f2:d5:f1:74:04 fdt_addr_r=0x12000000 fdtcontroladdr=7ded3a80 fdtfile=rockchipr=0x12100000 gatewayip=192.168.1.254 hostname=rock-3a ipaddr=192.168.1.253 kernel_addr_r=0x00 kernel_comp_size=0x8000000 loadaddr=0xc00800 netmask=255.255.255.0 pxefile_addr_r=0x00e000offset_f=0xffe000 script_size_f=0x2000 scriptaddr=0x00c00000 serial#=09103e09ce4edd27 serverserial@fe660000 stdin=serial@fe660000 stdout=serial@fe660000 vendor=rockchip Environment size: 916/126972 bytes  
So this is not finding the boot.scr with the bootflow scan -lb, so now is time to make it boot automatically.

Checking my system:
 
selu@rock-3a:~$ dd if=/dev/mmcblk0 seek=64 skip=64 count=32704 of=uboot.bin 32704+0 records in 32704+0 records out 16744448 bytes (17 MB, 16 MiB) copied, 0.564798 s, 29.6 MB/s selu@rock-3a:~$ strings uboot.bin | grep "U-Boot" U-Boot SPL board init command in your U-Boot project: ./scripts/stacktrace.sh dump.txt %s U-Boot SPL 2017.09-armbian (Sep 19 2022 - 14:20:01) U-Boot FIT Image with ATF/OP-TEE/U-Boot U-Boot(64-bit) *U-Boot U-Boot dtb ** Invalid partition type "%.32s" (expect "U-Boot") Enter U-Boot charging mode scan_dev_for_scripts=for script in ${boot_scripts}; do if test -e ${devtype} ${devnum}:${distro_bootpart} ${prefix}${script}; then echo Found U-Boot script ${prefix}${script}; run boot_a_script; echo SCRIPT FAILED: continuing...; fi; done U-Boot.armv8 command in your U-Boot project: ./scripts/stacktrace.sh dump.txt %s MU-Boot EFI: Relocation at %p is out of range (%lx) U-Boot 2017.09-armbian ## U-Boot bootargs: %s No valid device tree binary found - please append one to U-Boot binary, use u-boot-dtb.bin or define CONFIG_OF_EMBED.

And this is different from the bundled U-Boot:

I could not update U-Boot via armbian-install, somehow my rootfs on NVMe breaks install in the script ( I boot from SD with /boot in it ).
 
Not detecting the device ( using set -x )
++ sed -e 's/^.*root=//' -e 's/ .*$//' + root_uuid=UUID=a0d95135-003b-44d5-8efe-ef62615e7dea ++ blkid ++ tr -d '":' ++ grep UUID=a0d95135-003b-44d5-8efe-ef62615e7dea ++ awk '{print $1}' + root_partition=/dev/nvme0n1 ++ echo /dev/nvme0n1 ++ sed 's/\/dev\///g' + root_partition_name=nvme0n1 ++ lsblk -ndo pkname /dev/nvme0n1 + root_partition_device_name= + root_partition_device=/dev/ + exit 1  
I crafted a quick n'dirty script:
#!/bin/bash source /usr/lib/u-boot/platform_install.sh DIR=/usr/lib/linux-u-boot-current-rock-3a root_partition_device=/dev/mmcblk0 write_uboot_platform "$DIR" "${root_partition_device}"  
 
And I can confirm that u-boot was updated in SD and now works fine! YEEHAA!
