Currently it is not clear whether we support regular expressions for the setting "List of user agents to exclude".
In the list of IP addresses it says
Regular expressions such as /^sess.*|.*[dD]ate$/ are suported.
Regular expressions such as /^Good-example-of-regex-here$/ are supported.

Note: Regular expressions are currently not supported for useragents. See https://github.com/matomo-org/matomo/blob/7b6a14626960795b0acdf4a064cd3982d7704f2b/core/Tracker/VisitExcluded.php#L342-L356
Thanks for your reply @sgiehl.
Is there any plan to add regular expression matching for "list of user agents to exclude" in the future, or should I assume that we (Ubiquity Press) will need to implement this feature ourselves?
@simoncrowe the issue is currently not planned within the next releases. If you would contribute the changes needed for that in a PR we would be happy to review and merge that.
Alternatively if you would like to sponsor the development of that feature, feel free to get in touch with us: https://matomo.org/faq/new-to-piwik/faq_21953/
