You can by adding to your HOME/.ssh a config file:

Host wpengine 
user git
hostname git.wpengine.com
IdentityFile ~/.ssh/myPrivateKey

You can add as many 'Host' entry as you want, each one with a different IdentityFile

See for instance "Multiple SSH Keys settings for different github account"

#activehacker account
Host github.com-activehacker
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_rsa_activehacker

#jexchan account
Host github.com-jexchan
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_rsa_jexchan

You can then use the scp syntax for cloning your repo:

git clone github.com-activehacker:activehacker/gfs.git gfs_jexchan

(instead of ssh://git@github.com/activehacker/gfs.git, which wouldn't be able to reference a specific private key and would always fall back to id_rsa.)
