You can turn it off at "Control Panel\Hardware and Sound\Power Options\System Settings" by deselecting "Turn on fast startup" in admin mode. It has barely any difference either way, at least when the C drive is an SSD. However, you should turn on UEFI Fast Boot (in the firmware settings) which lets Windows do more of the initialization at startup and fewer firmware drivers are loaded. Fair warning that on my motherboard turning on UEFI fast boot can make it difficult to get back into the firmware (BIOS). Need to completely shut down by turning off the PSU and waiting for like a whole minute, otherwise the motherboard stays powered.
edit: It also doesn't dump full RAM, just a bunch of drivers and stuff like that which it reuses.
If you have a Linux distro installed too, just use grub and you'll never have issues getting to the bios again
