You can use the rdb command from redis-rdb-tools with the -c protocol option to output redis commands representing the data in the RDB file, and pipe them into a redis instance using netcat, socat, or similar.
Unfortunately, this python package was built for now unsupported python 2.7 and 3.5 and has not been updated since 2020 (see FAQs).

In my case, the version number 10 that doesn't work with redis-rdb-tools.
I have to use an alternative: https://github.com/leonchen83/redis-rdb-cli
