Give ground cannot be used in this way. From Collins English Dictionary:
to draw back or retreat:
"But as more and more men crossed the drawbridge, the castle defenders were forced to give ground"
"She leaned over his desk, pushing her face towards his, stopping uncomfortably close as he refused to give ground."
You may be thinking of a somewhat similar phrase, to give centre stage (from Merriam-Webster):
The middle section of a theater's stage:
"The actor stood alone at center stage."
A main or very important position:
"As we wrap up work on the old project, a new one moves to center stage."
"The issue is expected to take center stage in the elections."
It is not uncommon to give someone an important position so that they can demonstrate that they are capable of performing in that position.
