Install Arch on a different drive

[Thunderbottom]

Is it possible for the script to install Arch on a totally different drive than the one with macOS? This is because I'm using a 128GB SSD as my macOS boot drive, and I don't want to disturb the partitioning on that SSD. What I have instead is a 500GB HDD connected to the Mac internally alongside the SSD. So is there a way to install Arch on the HDD rather than the SSD? Thanks :)

This is what my partitions look like -

/dev/disk0 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *120.0 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
