You need a 14-1 pin Trusted Platform Module (TPM), as specified on page 1-26 of the mobo user manual.
Once installed, it will be detected by the firmware and present new options on the user BIOS.
These are made by a variety of manufacturers. And they're more than just security "tokens", RAS-128 PRNGs, or cypher/password tables ... they're active cryptologic circuits with their own onboard processing and memories.
ASUS happens to sell the best consumer model available, the most recent Infineon part with a pretty black PCB which doesn't clash with ROG mobos:

(While crypto modules are legally unrestricted "over the counter" stuff listed in many vendor inventories, I have learned that in reality they can be sort of difficult for consumers to obtain in Canada. You can still get one if you're persistent, but they're always "backordered" or "out of stock" or subject to other costs and delays which make actually procuring one a bit of a hassle ... I suspect our border agents are apprehensive about letting Canadian citizens have better crypto than Canadian government has, lol. I basically gave up on the stupid time-wasting games and obtained Supermicro TPMs through enterprise channels, better crypto perhaps, but alas they have ugly cheap industrial generic green PCBs.)

Yes, Windows BitLocker can encrypt data without a TPM. But it's software crypto, not hardware crypto. It's not as secure.
The TPM is not just a passive hardware token which stores crypto keys and passwords ... it also has active "black box" cryptocircuitry (and confidential anti-tampering self-destruct mechanisms) and it's married to one specific platform (motherboard, BIOS, etc). BitLocker crypto involving a TPM cannot be decrypted on any other hardware or motherboard or TPM, the drive cannot be installed/copied to another machine for brute-forcing because part of the crypto algorithm runs in the TPM itself. BitLocker crypto lacking a TPM can be copied/moved to any other (or any number of) machines for brute-force decryption.
That being said, BitLocker's software crypto is secure enough for pretty much anyone who isn't a tinfoil-hat enemy of the state, lol. And BitLocker welded shut with a TPM padlock can be critically problematic if the motherboard or TPM happens to die, there's no way to migrate or recover the data (by design!) if the original machine no longer works.

There is currently a debate about whether TPM is actually more secure or not.
