the current text of IBB (XEP-0047) doesn't mention discovery support.
There isn't a feature to announce support for IBB.
Maybe it should include something like (copied from XEP-0261):
To advertise its support for the In-Band Bytestreams, when replying to
Service Discovery information requests an entity MUST return URNs for
any version of this protocol that the entity supports -- e.g.,
"urn:xmpp:ibb:0" for this version (see Namespace Versioning regarding
the possibility of incrementing the version number).
Example N. Service discovery information request
<iq from='romeo at montague.lit/orchard' id='uw72g176' to='juliet at capulet.lit
Example N. Service discovery information response
<iq from='juliet at capulet.lit/balcony' id='uw72g176' to='romeo at montague.lit
In order for an application to determine whether an entity supports this
protocol, where possible it SHOULD use the dynamic, presence- based
profile of service discovery defined in Entity Capabilities. However, if
an application has not received entity capabilities information from an
entity, it SHOULD use explicit service discovery instead.
