Hi, dear!
Welcome to our community!
You should download the SUSE Linux OS on the official website.
The link is:
https://www.suse.com/download/sles/
For both x86 and ARM, you need to download the following two items:
SLE-XX-Installer……
SLE-XX-Packages……

If you can give me the exact version, I'll show you the exact package name.
You can boot it using Installer.
Best wishes!
