I don't believe there is such a thing, tho there are non-productive

What he may have really been asking is can you load Avref with to
large of a capacitor.  I believe the answer to that is 'yes'.
Anything much beyond 1uF or so probably is not useful.

A good place for him to start would be here:

"A bypass-capacitor dialogue peels back the layers, Part 1

The low-glamour but extremely vital subject of bypass capacitors and
decoupling gets additional investigation through a basic dialogue"

Also follow the links at the end.
