It is possible if a bit convoluted [1, 2]. When I looked into it last year it seemed the good guides were focused on Clevis & Tang with a separate server (i.e. your PC at home on your network would boot but if away from the Tang server the PC would fall back to password). In a quick look it seems they may simply support TPM2 now although I haven't looked into how/if this is different to the article.
