The docs suggest otherwise. The value is a list addresses, and the whole thing is ignored "if none of them are the correct type". I presume the correct type is one that’s been selected from MX records, or an option in a router or transport. So, if Exim has already decided to use IPv6, then then this option will be ignored and "the system’s IP functions choose which interface to use if the host has more than one".

I think the easiest thing to do is to say

disable_ipv6 = true
or
dns_ipv4_lookup = *
