I think they don't.
Since RBC do not contain nucleus, which form continuous membranous structure with the rough ER, both nucleus and rER may be absent in the RBC.
If this is true, RBC can not secret proteins. And all proteins they synthesize are not glycosylated.

I would like to add some more information regarding the role of RBCs in protein secretion or manufacturing, to my knowledge pool.

Am not sure about ER system but it is not correct to say that RBCs do not have nucleus. They have nucleus but are lost during maturation. Their membranes are also glycosylated - as for example the ABO antigens.
Yes, but I meant mature RBC. Maybe mature RBC no longer need to synthesize proteins. (?)
Without nucleus, no mRNA can be produced.
