Answer
No, this isn't currently configurable — the automatic-loading behavior seen in the Record Selector isn't available as an option for standard List views, which remain manual-'Show more'-only. This is a known usability gap rather than a hidden setting; raising it as a support case (so it can be forwarded to R&D, or tracked via IFS Ideation once available to your organization) is the way to push for this being added, since there's no current plan or workaround to enable it yourself.
