InnoDB size

I have a MySql RDS service on AWS.
My Innodb_buffer_pool_size is 24G and the machine total RAM is 32G.
When I tuned the memory and I look into the Cloudewatch of AWS, I can see that the innodb buffer pool is taking only half of his memory that dedicated for him (only ~12G instead of 24G).

I understand that the LRU Algorithm remove old pages from the Cache, but is there a way to force hime to use all the memory (load more data and indexes to the cache? but I'm not referring to use MIsam or Memory engine)

IF not, Should I reduce the size of the InnoDb_Bufferpool_size?

extra details:
innodb_buffer_pool_instances = 8
innodb_buffer_pool_chunk_size = 128M
