The config.txt of the Rasperry Pi's supporting Wi-Fi and Bluetooth (i.e. zero W, zero 2 W, 3, and 4) switch the Bluetooth function to use the mini-UART (ttyS0) and restore UART0 (ttyAMA0) over the GPIOs 14 and 15 (as per miniuart-bt-overlay.dts[1]). All of them turn "on" the parameter krnbt to autoprobe the bluetooth driver. According to the README.md, the dtparam krnbt is now defaulting to "on" since linux-raspberrypi 6.1.y[2]; it was defaulting to "off" before[3]. This removes the dtparam=krnbt=on from these config.txt files since the value set is actually the default value.
