No

You can't ask everybody to upgrade to 2.15 at once. And the formatMsgNoLookups option is available to log4j ≥ 2.10 only.

Thanks to LOG4J2-703, I think it's quite safe to remove org/apache/logging/log4j/core/lookup/JndiLookup.class from log4j-core-*.jar as a workaround. Just zip -q -d log4j-core-*.jar org/apache/logging/log4j/core/lookup/JndiLookup.class to disable ${jndi:...} functionality completely.

I posted all log4j-core jar with JndiLookup.class removed at https://github.com/zhangyoufu/log4j2-without-jndi for reference. Simple local test looks promising.
