Recent Raspberry Pi 4 units have natively supported 1.8 GHz out of the gate. Now, the Raspberry Pi Foundation has brought 1.8 GHz support to all revisions of the Raspberry Pi 4 with the latest version of Raspberry Pi OS.

Not true.
QuoteBut some of you may have noticed another upgrade. Users with recent Raspberry Pi 4 devices will find that their default turbo-mode clock has increased from 1.5GHz to the 1.8GHz used on Raspberry Pi 400. "Recent" in this case means any 8GB Raspberry Pi 4, or a 2GB or 4GB board with the extra components circled in the image below. This is the dedicated switch-mode power supply ("switcher") for the SoC core voltage rail, and was introduced when we shuffled the allocation of switchers to rails to support 8GB.
The image you used even circled the necessary components.
Almost all of them should already be able to get to 1.8 GHz, but not by default with the Bullseye upgrade.
