How to get rid of busybox

Hi folks,
I have dozens of WD My Clouds (The narrow white ones) with different capacities. They used to have a regular debian Linux I could ssh to. However, I just purchased two new 6TB devices and I was quite unhappy to learn that busybox now limits the commands I can execute on the shell. apt is unavailable now which makes it hard/impossible to use some of my scripts which worked perfectly fine on my other MyClouds.

Is there any chance of getting rid of busybox and use the regular Debian again?

Thanks a lot for any help on this!
