RK3582 is a down-binning variant of RK3588S. The availability of its GPU (mali-g610), CPU (two of four cortex-a76 cores) and VPU (one of two decoders/encoders) is determined by silicon lottery. Rockchip disabled this uncertainty by default in u-boot bootloader. And there are u-boot patches in the Armbian repo to force them re-enabled and shell scripts on Radxa forum to verify the availability of hardware units.

The CPU has little effect on RKMPP hardware transcoding, and half the VPU will only halve the transcoding speed. But without the GPU you lose HDR to SDR tone-mapping.
