Mount vendor image from Android

Hello together,

is there a possibility to mount the vendor image from the Android installation image? So far I
got https://dl.khadas.com/products/vim4/firmware/android/vim4-android-11-64bit-v220826.img.xz
extracted which lead to the following files:

_aml_dtb.PARTITION: gzip compressed data, from Unix, original size modulo 2^32 0
aml_sdc_burn.ini: ISO-8859 text
aml_sdc_burn.UBOOT: data

vendor_boot_a.PARTITION: data

I was able to convert super.PARTITION via simg2img and mount it with an offset. Unfortunately the vendor folder is empty so I guess it is within one of the other partitions. Can s.o. guide me to get those
others mounted?

Thanks,

Christoph
