Can You Use A Sealing Grease With Teflon Tape On Old Plumbing?

I am trying to put a new galvanized nipple into an old, corroded galvanized tee. It is nearly inaccessible, and swapping out the old tee will be a huge mess I hope to avoid (concrete, tile, etc broken out and impossible to match). Should I use only teflon tape or teflon putty, or can I also use a grease. If I use grease , what type- I am inclined to white lithium based but don not know how it holds up in water pipes.There is no old styler pipe dope in the local market.
I would use the tape as Lithium based means introducing dissimilar metals in a water system. More corrosion ahead.. we used to have the same problem when we used molybdnum based grease when fitting stainless bosses to Yorcalbro pipe. The grease caused the steel to crumble…in the end we were advised to use petroleum jelly (vaseline)
