Short answer. No. Article 1049 of the Civil Code expressly states that acts of mere preservation or provisional administration do not imply acceptance of the inheritance, so long as those acts did not assume the title or capacity of an heir. Temporarily protecting estate property from damage generally fits that description.
What the law says
Acceptance may be express or tacit. An express acceptance must be made in a public or private document. A tacit acceptance is one resulting from acts by which the intention to accept is necessarily implied, or which one would have no right to do except in the capacity of an heir

Express and tacit acceptance
Article 1049 of the Civil Code opens by defining the two ways an heir accepts an inheritance: "Acceptance may be express or tacit. An express acceptance must be made in a public or private document. A tacit acceptance is one resulting from acts by which the intention to accept is necessarily implied, or which one would have no right to do except in the capacity of an heir." Tacit acceptance is about conduct that necessarily implies the intention to accept, not conduct that merely touches the estate.
The specific exception for preservation and provisional administration
The article closes with the exception that answers your question directly: "Acts of mere preservation or provisional administration do not imply an acceptance of the inheritance if, through such acts, the title or capacity of an heir has not been assumed." Taking temporary steps to protect estate property from damage is squarely the kind of act this sentence describes — it does not, on its own, count as tacit acceptance.
Why the exception has its own condition
The protection is not unconditional. It applies only "if, through such acts, the title or capacity of an heir has not been assumed." That means the same physical act of caring for estate property could read differently depending on how it was carried out and presented — simply safeguarding assets from damage is one thing, but acting as though you were already exercising an heir's authority over the estate is another, and the exception does not cover the latter.
Applying this to what you actually did
If what you did was limited to protecting the property from damage — the kind of act anyone might reasonably take to keep an asset from deteriorating while its ownership is being sorted out — and you did not, through those acts, present yourself as already holding the title or capacity of an heir, Article 1049 treats that as falling outside tacit acceptance. What matters is not that you touched or looked after the property, but whether doing so implied you were claiming the estate as your own.
