Hello! With March of the Multitudes and convoke, if I have a way to untap a creature, say with the Vizier of Remedies-Devoted Druid combo, can I tap the Devoted Druid as many times as I can to pay into the convoke cost?
No, this won't work. You tap creatures for convoke at the same time you pay mana and other costs for the spell. It's too late to activate any abilities, even mana abilities. Of course, you could just generate a million mana with your Druid before you start casting March of the Multitudes and take advantage of the combo that way.
