First you should upgrade your machine to PHP 7.4, it you haven't checkout this great guide from Brent 

the short version is to do these steps using homebrew:

brew upgrade php

At this point your machine should be using PHP 7.4 but Laravel Valet may still be using PHP 7.3.

Upgrade Valet:

Update composer

composer global update

Next update Valet

valet install

Now to tell valet to use the latest version of PHP
