No. You have to (in Chrome) right click the text and click "Inspect". A console will open on the right. Look for code about the footer copyright then copy the code and use the display: none
I can't really explain any clearer as all themes are different.
Example...
It could be something like this ...
.footer-content, .copyright-content {
margin: 0 auto;
max-width: 1576px;
}
Change it to this ...
.footer-content, .copyright-content {
display: none;
}
Then paste it into Appearance/Customize/Additional CSS and save.
