SAFe (Scaled Agile Framework - for which I will not provide the link because they don't deserve it) is worthless shite! It's just a bunch of practices developed elsewhere, rebranded by a cabal of consultants to cream money out of large organisations. The only additions it brings are there to placate management by helping mascarade traditional waterfall processes and hierarchical structures as "agile" - it does little to nothing new to actually change the org! Save your money and go open source with your processes. SAFe is bollocks!
