Ripening of existing pods is effected by time and temperature. It uses no energy from the plant once the pods are full sized, and will not be sped up by pulling off new blooms. Well there is the minor exception that the plant continues to pump water to them so that uses a tiny bit of energy but not energy that would change ripening rate... a dried out pepper stops ripening.

However pulling off new blooms will allow the plant to put more energy into growing to full size, any pods that are not there yet. With a month to go you might get a significant % ripe on the plant before 1st frost but you can always put a blanket over the plant if it doesn't get very cold overnight to give it a little extra time, or bring inside if potted, or in worst case / last resort you can pull and hang t inside where it stays above freezing then you can take your time picking them off later.
