Not correct. A MBR is necessary for either BIOS or UEFI boot from this
kind of device.

I just read the following on the necessity of some kind of an MBR
https://www.howtogeek.com/193669/whats-the-difference-between-gpt-and-mbr-when-partitioning-a-drive/

GPT drives tend to include a “protective MBR.” This type of MBR says that the GPT drive has a single partition that extends across the entire drive. If you try to manage a GPT disk with an old tool that can only read MBRs, it will see a single partition that extends across the entire drive. This protective MBR ensures the old tools won’t mistake the GPT drive for an unpartitioned drive and overwrite its GPT data with a new MBR. In other words, the protective MBR protects the GPT data from being overwritten.

Windows can only boot from GPT on UEFI-based computers running 64-bit versions of Windows 10, 8, 7, Vista, and corresponding server versions. All versions of Windows 10, 8, 7, and Vista can read GPT drives and use them for data—they just can’t boot from them without UEFI.
