Short answer. Yes, once. Where the dissolution was decreed on your joint petition, your agreement to revive the former regime is a listed ground for a motion in that same case. But the article then bars any voluntary separation of property afterwards, so the reversal is permanent.
What the law says
(7) When after voluntary dissolution of the absolute community of property or conjugal partnership has been judicially decreed upon the joint petition of the spouses, they agree to the revival of the former property regime. No voluntary separation of property may thereafter be granted.

Regret alone is a sufficient reason here
Most of the instances in this article are triggered by an external event — an absence ending, a sentence served, parental authority restored. This one is not. The ground is simply that the spouses who jointly asked for the dissolution now agree to the revival of the former property regime. No change of circumstances has to be proved and no fault has to be shown. That makes it the most accessible of the seven grounds and, because of the sentence that follows it, the most consequential to invoke.
It has to be the same regime and the same case
What you may revive is the property regime that existed between them before the separation of property. If you were under absolute community, absolute community is what comes back; you cannot use the motion to install a conjugal partnership instead because that now suits you better. And the motion is filed in the same proceedings where separation of property was decreed, so the court that granted the dissolution is the court that undoes it. Find the decree and the docket number before doing anything else.
The bar is absolute and it is the point
Read the next sentence as part of the bargain: No voluntary separation of property may thereafter be granted. The law will let a couple change their minds once and will not let them keep changing them, because a property regime that oscillates is unworkable for everyone who deals with the spouses. So a couple who revive and later drift apart again cannot simply repeat the exercise. That is the trade, and it deserves a harder conversation between the two of you than the original dissolution probably received.
The inventory does the real work
Revival is governed by Article 67, which requires an instrument stating the properties each spouse contributes anew to the restored regime and those each retains as separate. Between the dissolution and now, each of you has been acquiring property in your own right, and the instrument is where all of it is sorted. Prepare a complete list — titles, accounts, vehicles, business interests, debts — with dates of acquisition, and be candid about it. An inventory that omits things is the defect that surfaces years later, when it is expensive.
