This is probably unrelated to fingerprinting the user. Most likely they
do that in order to check that the browser is able to use certain
features they use (rather than using feature detection instead).
Or maybe they do that just to force their clients not to use outdated
(and thus probably insecure) browsers.

In any case, using an User Agent which is not common (such as an old
browser, or a made-up one) will actually make you stand out, not
conceal you.
