The current usage of the term "conservative" is just a fig leaf to hide the less-palatable aims of a radical fundamentalist agenda aimed at attacking most modern aspects of our society. Go find any definition of conservatism written by traditional conservative intellectuals, and you will find Trumpists are directly opposed to most of it.
Basically, conservatives got increasingly angry (because things inevitably do change), so they decided to give up on conservatism and flip the table instead. One intellectual upstream of Trumpism is the writings of Mencius Moldbug (Curtis Yarvin), who laid out how mere conservatism wasn't enough because "Cthulhu swims left" still, and coined his philosophy "reactionary". This also ties into one of the commonly-described dynamics of fascism - invoking an idea of some imagined idyllic past, as a reason that the current society needs to be attacked and destroyed.
I had never voted for a major party candidate in a national election until Biden 2020 and Harris 2024. I consider those solidly actually-conservative votes, and partially attribute them to my getting older and more actually-conservative.
