The d-parameter was introduced with the hard-fork from Byron to Shelly.
This was implemented for the purpose of slowly allowing public stake-pools to produce blocks.

<p>Nothing is mentioned anywhere if, and according to which policy, IOG can move the d-“slider” in the other direction, to again start producing more centralized blocks whenever they deem this necessary. Probably a question only Charles or Duncan can answer.</p>

Could the d-factor still be changed, to revert to more centralized block production by IOG?

Cardano has three different pillars of decentralization:

The first pillar: block production. Once d hit 0, this pillar was fully decentralized.

The second pillar: networking. It means how nodes find each other and pass on this information. Currently, this is a topology file and it will be replaced by P2P discovery.

The third pillar: governance. The way to vote on all protocol parameters (like d) and updates and access fundings of the treasury.

So to answer your question: yes, theoretically, it would currently be possible to increase the d-parameter again. But should IO do so, it would certainly be a disastrous signal.
