Absolutely--but the only real question there is whether one holds to the "T" - the rest falls out by necessary consequence (though, more importantly, each letter in that acronym is the clear teaching of Scripture as well). The "T" is simply that man by his rebellion was cursed (Gen. 3) and became totally lost, and totally unable, and totally unwilling, to save himself - he became spiritually "blind" (John 2), an "enemy" of God (Rom. 5), a "child of wrath by nature" (Eph. 2). Having sword allegiance to the Serpent instead of his Creator, he chose friendship with the Serpent and enmity with God. This is our state before the Spirit of God (monergistically) grants us new life. Like Lazarus in the tomb, we cannot even "see" the kingdom, let alone enter it, because we have been justly cursed. It takes a divine miracle--regeneration--to open our eyes, change our hearts, to see the truth (John 2).
But there's more to "Calvinism" than the "five points": "[How Many Points?](https://the-highway.com/how-many-points_Muller.html)" The "five points" were not "a thing" until the 17th-century Synod of Dordt (~50 years after Calvin's death), when they were formulated in opposition to the Arminian Remonstrants. And it was little more than a reaffirmation of that Paulean-Augustinian stream that leads to salvation being by grace alone, by faith alone, in the work of Christ alone, according the authority of scrpture alone, and to the glory of God alone.
(I sincerely appreciate this back-and-forth. These are important matters--literally matters of eternal life and death--and thus are far more worth talking through than most other things.)
