[Star Wars] Did the Battle of Scarif directly lead to the ending of the Imperial Senate?

Grand Moff Tarkin’s opening line in A New Hope is to proclaim that the Imperial Senate will no longer be off any concern, because he had just received word that the Emperor had dissolved it.

Canonically, this whole scene takes place within hours or days after the Battle of Scarif.

Was that battle the excuse the emperor used to dissolve the senate? I’m assuming that eradicating the senate was eventually on Palpatine’s vision board, but with the successful testing of the Death Star coupled with the irritation of the attack on the Scraif, was this the trigger?

They're separate incidents at the same time. The Senate was being dissolved by the Emperor as the Death star was near completed. Even had it not been finished he would have disbanded the Senate in favor of the Moff council that he had greater loyalty from.
