Short answer. Not through conventional subrogation. Article 1301 of the Civil Code requires the consent of all original parties — including the debtor — and of the third person stepping in. Without the debtor's agreement, conventional subrogation does not occur, and the third person cannot step into the creditor's legal shoes under this mechanism.

What conventional subrogation is
Subrogation is the substitution of one person in the place of another with respect to a legal right or claim. In the context of obligations, subrogation typically means a third party steps into a creditor's position and acquires the right to collect the debt from the debtor. Conventional subrogation is the kind that arises by agreement among the parties — as distinguished from legal subrogation, which the law imposes automatically in defined situations. Article 1301 governs the consent requirements for the conventional kind.
All three must agree
Article 1301 is explicit: conventional subrogation requires the consent of the original parties and of the third person. 'Original parties' means both the creditor and the debtor. So yes, the debtor must consent. The third person stepping in must also consent. Three parties, three consents — no shortcut. The rationale is that subrogation changes who the debtor must deal with. A debtor may have chosen to contract with a specific creditor for good reasons — trust, specific terms agreed, or personal relationship — and the law does not allow the creditor to hand those rights to a stranger without the debtor's agreement.
How this differs from legal subrogation
Legal subrogation is a different matter. It occurs by operation of law in specific situations — for example, when a third person pays the debt of another with the creditor's consent, or when a co-debtor pays the full debt. In those cases, the third person is subrogated to the creditor's rights without needing to meet the three-party consent requirement of Article 1301. The Civil Code provides for legal subrogation in separate provisions. If you are trying to subrogate without the debtor's consent, the question is whether your situation falls under one of those legal subrogation provisions.
Practical implications
If you are a creditor who wants to bring in a third party to take over your credit — perhaps as part of a business restructuring or sale of receivables — you need the debtor's cooperation. Similarly, if you are a third party looking to be subrogated to a creditor's rights in a specific obligation, obtain all three consents in writing before proceeding. An arrangement purporting to subrogate you without the debtor's consent is not a valid conventional subrogation, and you may find you cannot enforce the credit against the debtor on that basis. A lawyer can help structure the arrangement properly.
