Delete or disable a Method Modifier

Anyone know a bit of meta or other way to delete a MM or disable a MM from firing?

package Stuff;

with 'OtherStuff';      # run()

after 'run' => sub { @_[0]->check };

sub check { # yadda... }

__PACKAGE__->meta->make_immutable;no Moose;1;


my $p = Stuff->new;
# delete or disable MM so I can test check() autonomously
$p->run;

$p->check;
