Short answer. No. A court may authorize an administrator to sell estate property that would benefit the heirs even if the sale is not needed to pay debts or expenses, but that authority cannot be granted if the sale would be inconsistent with what the will provides, so a specific bequest is protected from being sold off this way.

When a court can authorize a beneficial sale
During estate settlement, the executor or administrator may ask the court for authority to sell part or all of the estate when doing so would be beneficial to the heirs, devisees, legatees, and other interested persons. This authority is broader than the ordinary rule that property is sold only to pay debts, legacies, or administration expenses — the court can approve a sale for the heirs' benefit even where none of that is at stake, so long as written notice goes to the heirs, devisees, and legatees with an interest in what is being sold. Written notice to the heirs, devisees and legatees interested in the property to be sold is itself a condition of the authority, not a courtesy.
The limit: a will's specific provisions control
That authority has a firm boundary. The court cannot grant it if doing so would be inconsistent with the provisions of a will. Where a testator specifically bequeathed a piece of property to a particular heir, authorizing its sale over that heir's objection would contradict the very will the probate court is supposed to be giving effect to, so the rule blocks the sale rather than letting a general notion of what is beneficial override what the testator actually wrote. The protection does not depend on the heir having objected in advance, either: the rule addresses the court's own power, and it withholds the authority itself whenever the sale would collide with the will's terms.
What happens to a sale that is properly authorized
Where a sale of unbequeathed or otherwise available estate property is properly authorized because it is beneficial and no will provision stands in the way, the proceeds are not simply absorbed into the estate at large — they are assigned to the persons entitled to the estate in the proper proportions. This keeps the safeguard consistent on both ends: the sale itself cannot override a testator's specific intent, and once a permissible sale does happen, the money it generates still has to reach the right heirs in the shares the law or the will assigns them.
