This Rockchip system uses the legacy msdos partition table, right? (No UEFI, thus no GPT). With this partition table it should be possible and is confirmed to be working, to set the bootable flag for a partition AFAIK (like an ext2 /boot partition).
In Diederik's report the partition table is GPT, not MSDOS. Indeed the default disk label (partition table) for the arm64 architecture is GPT, regardless of whether the sub-architecture is EFI or not (see <https://salsa.debian.org/installer-team/partman-partitioning/-/blob/master/lib/disk-label.sh>).
