there is no direct or simply way to configure what we need in question.
But it can be done by editing the User Shell theme that is in use.

if you are using default theme in 18.04, below is the way to achieve.

first take back up of /usr/share/gnome-shell/theme/ubuntu.css file.

now open the file with you favorite text editor, mine is gedit, so

sudo -H gedit /usr/share/gnome-shell/theme/ubuntu.css

go to line number 1205 and find the below content.

.dash-label {
  border-radius: 7px;
  padding: 4px 12px;
  color: #eeeeec;
  background-color: rgba(46, 52, 54, 0.7);
  text-align: center;
  -x-offset: 8px; }

Change it to 

.dash-label {
  border-radius: 7px;
  padding: 4px 12px;
  color: #eeeeec;
  background-color: none;
  font-size: 0pt;
  text-align: center;
  -x-offset: 8px; }

save the file & close. Reboot to see the change.

if you use different User-Shell themes, you may find same content and editing it as above.
