That is sometimes partially so, for some. However, there are many fundamental, bedrock principles that conservatism is built upon. These principles (liberty, natural law, self-reliance, religious freedom, etc.) don't change; even though policies based on them change as circumstances warrant.
Today especially, “ ‘conserve the status quo’, including worship of the current Establishment” is in direct conflict with “liberty, natural law, and self-reliance.”
Many so-called “conservatives” and “conservative stalwarts” including George Will and the late Charles Krauthammer, seem willing to forgo the latter in favor of the former.
