Yes, but why pay for it if `sudo apt install zedis` works? Many use-cases for redis growing out of memory would actually be ok if it stores old values on disk for you and keeps hot items in cache (and does compression).
It’s not feasible to do that in a single threaded system.
The main drawback of disk persistence is that you need a log of memory to keep the file buffer open and pointers.
If the key you’re looking for is not on disk, you’ll get awful results, the rdb format will give you worst then Postgres performance. You have to use another file format to optimize for a larger cache

Why not use a managed Redis or a large memory instance and run Redis yourself then? They aren't that much more expensive if you need to move fast.
