Yea, Its in the block config that can be set at the global config level
or the block level, or the port level.

https://github.com/guruofquality/gras/blob/master/include/gras/block_config.hpp

https://github.com/guruofquality/gras/blob/master/include/gras/top_block.hpp#L24

https://github.com/guruofquality/gras/blob/master/include/gras/block.hpp#L42

Its also available in the wrapper set set_max_noutput_items on the
blocks, it just didnt get into the second parameter for the run/start
API calls. I can add it...

Just curious... What are you trying to do at a high level? Constrain the
available buffer that a block can produce (without upstream consuming)?
Constrain the maximum number of items in a single call to work? etc..
