Align TOC Centre SOMETIMES

Hi there, I’m wondering if it’s possible to set the table of contents to align center on some posts only.

I create pillar-style posts for broad topics, where I design the post a little different, and rather than having a sidebar with everything left aligned, I center some text and headings.

I’m wondering if there’s a code I can use to center align the TOC on command, and not interfere with the usual alignment on the majority of my posts?

Thanks!
