Windows 10: BitLocker flaw revealed

A recent flaw in BitLocker protected drives were discovered regarding Thunderbolt and DMA attacks and one of the mentioned mitigations to this type of attack is enabling the Kernel DMA Protection mode. I followed the below steps as directed and this option is still disabled. I'm running Win10 v1803 and plus, I updated my UEFI firmware to the latest update on my laptop E6440. My question is, will this be enabled in v1809 or will I need to purchase a whole new laptop?
