Yes.
(from spec.txt , exim v3)
percent_hack_domains Type: domain list Default: unset
The 'percent hack' is the convention whereby a local part containing a
percent sign is re-interpreted as a remote address, with the percent
replaced by @. This is sometimes called 'source routing', though that term
is also applied to RFC 822 addresses that begin with an @ character. If
this option is set, Exim implements the percent facility for those local
domains listed, but no others. The option can be set to '*' to allow the
percent hack for all local domains.
If options are set to control message relaying from incoming SMTP
envelopes, they are also applied to relaying that is requested via the
'percent hack'. See section 46.4.
set
percent_hack_domains = :
in your exim.conf to disable that sort of relaying.
