Jólnir - How to prevent laptop do suspend when locking it

I know that's it's not a new behavior but it's really annoying when I leave my desk 2 minutes to wait for the compute to wake up when I get back...

So, when I lock the compute, it goes directly in suspend mode whatever the setting I can set in Energy panel of the System settings...

Can I configure Elementary to prevent this behavior?

Thanks for any help !
