If you don’t have a setting it might be because you need to buy a tpm module like this one. You shouldn’t need to buy a new board. Your board should have a tpm header to connect the module to.

This TPM is only for ASUS fourteen minus one (14-1) motherboards: https://www.amazon.com/dp/B01DQQLH74?psc=1&ref=ppx\_yo2ov\_dt\_b\_product\_details
No it’s a physical connector as well that you connect to your motherboard, You can see here: Asus TPM-M R2.0 14-1 Pin TPM Module https://www.amazon.com/dp/B01DQQLH74/ref=cm_sw_r_awdo_QWWHW9S20D50TCMFX8GA
Be careful out there. While this is a TPM 2.0 module, the original firmware is still susceptible to the 2017 security issue, which means Windows will still not be sated. Happily you can update the firmware yourself. Look at the comments on the Amazon product page for pointers. It sucks Asus isn't supporting this product directly.
Just ran into this today. Built an ASUS x570 Prime Pro system recently, noticed the 14 pin TPM header on MB keyed on pin 14, so ordered a 14 pin TPM from amazon after some basic searching where it seemed there was only 2 possible modules.. a 14 pin and a 20 pin.

WTF ASUS¿
re: TPM: something like this should work on the MB I'm mentioning? https://www.amazon.com/Asus-Accessory-TPM-M-R2-0-Motherboard/dp/B01DQQLH74/ref=sr_1_fkmr1_2?ie=UTF8&qid=1487896553&sr=8-2-fkmr1&keywords=add-on+TPM+chip
re: USB This MB apparently has 1 USB controller only, does this mean, using Qubes on it, is not advisable ? or can you think of any work around? http://www.asrock.com/mb/Intel/H110M-STX/?cat=ManualS
