Is there a gentler way to install erlang?

I'm running asdf install on an Armbian device and installing Erlang is so CPU intensive that it stops responding to ssh requests. Seems like the parallelism might be a bit... aggressive. It's doing a lot of post-download work and I'm wondering if that's particular to Armbian. No precompiled binaries? Is there a flag I can set to reduce the number of jobs?

I have a handful of these devices so if there's a way I can transfer from one machine to the others short of cloning the disks I'd be interested in any pointers.
