Nope.  Dash does not have a governance system.   Governance implies that you can force a change.   The only thing the budget system can do is pay out a project that is submitted.

Proof:   Budget passed to increase block size to 2MB.   Result is still 1MB blocksize.  Of course, this proposal is used over an over to say Dash can increase the blocksize in 24 hours....um.   right....1 year and still no change.

The only ones that can control changes are those with access to github.  And even then, the code needs to be created and tested before it can be approved.

Charlie was spot on with the "Marketing over Tech".

To get you started on that blocksize increase, here is a start.
https://github.com/dashpay/dash/blob/master/src/primitives/block.h
/** The maximum allowed size for a serialized block, in bytes (network rule) */
static const unsigned int MAX_BLOCK_SIZE = 1000000;
change to
static const unsigned int MAX_BLOCK_SIZE = 2000000;
