The I3C Specification lists the maximum per-device capacitance on SCL and SDA, but the goal is that most or all devices will be well below that. Capacitance alone is not sufficient to determine maximum frequency on the I3C bus (as with any bus). It is important to consider maximum propagation length, effect of stubs, internal clock-to-data (tSCO) of the Slaves, as well as capacitive load.
