Test the value first, before the set, with a separate condition line.
warn domains = .... or whatever
condition = more whatever
condition = ${if =={$acl_m_foo}{1}}
set acl_m_foo = 2
Whether you prefer those separate last two lines or just:
set acl_m_foo = ${if =={$acl_m_foo}{1} {2}{$acl_m_foo}}
is largely a matter of taste, rather than there being a "right" way.
I would suggest that using magic numbers is probably not a right way.
Using more descriptive values which you can test against is
self-documenting, or use separate variables rather than overloading one.
