Bypass kdf step with LUKS2

Hi,

I have an unusual request. Is there any way to skip the PBKDF2 step
when a device is being formatted with LUKS2 or an additional slot is
being added?

Here's why I'm asking: I am using a high entropy 256-bit key as my
keyfile and the KDF step is unnecessary and does not improve my
security profile. If I am managing thousands of devices and want to
rotate the passphrases on them, this KDF step is becoming the major
bottleneck in performance.

Thanks
