If the minimal allocation is a /22 there is no written rule that one
should aggregate and announce the entire /22 it can be de-aggregated to
announce a /24 from the allocation for anycast purposes.

Question would be "who runs anycast and why?.If they form part of the
critical infrastructure there is room for them to apply additional /24
for anycasting as per the current AfriNIC IPv4 policy for critical
infrastructure.
