Hi Dariusz,
As far as i know - there is no built in functionality to change it, but you could use two custom approaches:
1. Create custom Form Rule with javascript below, and run it on opening the form:
document.querySelectorAll('.header-cell__name-value').forEach(h => { h.style.textAlign='center' })
This selects all table headers on the page, and centers the text, you could edit querySelector, to get specific table only.
2. Add custom global CSS:
.header-cell__name-value {
text-align: center;
}

Both have some disadvantages, none is perfect, but it's possible :)
