Most did not? The DNVP and Zentrum did, repeatedly and often, and they were by far the largest right-wing & centrist powers in the Republic.
Take a look at the party votes for the Enabling Act.
Absolutely not. Frankly, the enabling act is the perfect evidence of how wrong you are.
There were attempts by those parties to work with the Nazis leading up to the Enabling Act because there wasn't a majority and their government could not function at all. The parliament was split into 3 segments that would not work together: the Nazis, the Communists, and everyone in between. The Nazis were much more powerful than the Communists, but the two were a symbiotic pair, growing themselves off of the opposition to the other, actually quite aware that is what they were doing. Antifa vs groups like the Proud Boys are a recreation of this, Antifa more literally drawing from the same organization in Weimar Germany, attempting to push voters towards extreme positions by propagation of hate and violence.
But anyway, 3 groups: Nazis, Communists, and everyone else. At the time of the enabling act, there were 647 deputies: 288 Nazis, 81 Communists, 278 of everyone else. Nobody could establish a majority without including either the Nazis or Communists, there just weren't enough others to do that. The only thing they could do to try to run a functioning government was to work with one of those two, but neither could be given the helm, cause they both intended to dissolve the Republic anyway. So the right-wing parties tried to work on getting the Nazis to moderate unsuccessfully, and the left-wing parties tried to get the Communists to moderate unsuccessfully, and the deadlock persisted.
Which brings us to the Enabling Act. If, as you say, the DNVP and Zentrum were repeated allies of the Nazies, the Nazis could have formed a majority with either one of them. Either of those parties voting with the Nazis would give them the full power to govern, the Enabling Act would have been unnecessary. That didn't happen. Hitler was appointed Chancellor by the President (who funny enough also won his spot with a plurality rather than a majority because the Communists took their all or nothing stance) without the support of any party other than the Nazis themselves. Then the Reichstag Fire happened, whether you think it another misguided act of Communist accelerationism or a false flag by the Nazis, the result is the same, civil liberties were suspended under the Reichstag decree, and the Nazis arrested all of the Communists, and then began arresting the SPD. By the time of the vote, the outcome was foregone: if the Nazis couldn't get the vote they needed, they were going to arrest and imprison as many people as it took to get the vote they needed. Thus, the decision at the vote was not "do you want to give Hitler absolute power to enact law without the consent of parliament?" Rather, the question was "do you want to be in prison when Hitler gains that power".
Unless you truly believe that 8 entire other political parties over the course of a few weeks went from refusing to seat Hitler as chancellor to granting him dictatorial powers unanimously, the vote on the Enabling Act and the mass arrests and intimidation necessary to reach it should illustrate vividly that no other parties were playing ball with Hitler in that moment.
