Was there ever a real response / solution to the original question ?

Because I think I might have the same problem.
9800 -> Configuration -> Services -> Multicast - Wireless mDNS Bridging (enable or disable)
What is the equivalent CLI command ?
Our scenario is that it seems that Catalyst Center disables this single feature, on provision, and we would "just" create a CLI template that enables it. But we simply cannot find the added command in the configuration. Also in a "diff" of startup / running.
Documentation does not seem to cover this, only that you can see it enabled through show commands, but not "the" command to enable it.
Cheers - Thomas

- @Thomas Obbekaer Thomsen You must have Global Wireless Multicast Mode set to Enabled if
you want to enable Wireless mDNS Bridging

If you are looking for the related CLI commands ; checkout and install

@Thomas Obbekaer Thomsen

To Enable:
wireless multicast link-local

To Disable:
no wireless multicast link-local

Beginning with Cisco IOS-XE 17.6.1 and later, when you enable global wireless multicast (wireless multicast), link-local multicast bridging (which handles mDNS) is enabled by default.

To override what Catalyst Center is pushing and force-enable the feature, you can add the following block to your CLI template:

wireless multicast
wireless multicast link-local

@Thomas Obbekaer Thomsen fyi also see https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/17-18/config-guide/b_wl_17_18_cg/m_link_local_bridging.html

Lots of confusion around this feature and the change in behaviour after 17.6 - see https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwd59093 - 47 customer TAC cases attached!
