I have committed changes to TLUtils.pm:
--- a/Master/tlpkg/TeXLive/TLUtils.pm
+++ b/Master/tlpkg/TeXLive/TLUtils.pm
@@ -2348,6 +2348,18 @@ sub setup_programs {
   my ($bindir, $platform, $tlfirst) = @_;
   my $ok = 1;

So if you set
	TEXLIVE_PREFER_OWN=1
in the environment (for installer and tlmgr), then those programs
shipped by TeX Live are prefered over those from the system.

The installer will be upated probably today already, after installation
the texlive.infra will still be old and you need to install from 
tlcritical.

Best
