Recent Apps 'Lock' on Pixel 2..?

[PixelBen]

Literally the only thing I miss from my Oneplus 3 is the Recent apps 'lock' (detailed in this link: https://www.techrepublic.com/article/how-to-make-use-of-the-android-nougat-recent-apps-lock/) - i'm always accidentally closing apps that I'd like to stay open.

Is there any way to enable this feature on the Pixel 2?

Thanks,
B
