You can use #send or #instance_eval, e.g.

irb(main):001:0> class F
irb(main):002:1> protected
irb(main):003:1> def x;1 end
irb(main):004:1> end
=> nil
irb(main):005:0> f=F.new
=> #<F:0x7ff94460>
irb(main):006:0> f.x
NoMethodError: protected method `x' called for #<F:0x7ff94460>
         from (irb):6
         from :0
irb(main):007:0> f.instance_eval { x }
=> 1
irb(main):008:0> f.send :x
=> 1
irb(main):009:0>
