No need to give anything up.
Just enact the Constitution as written.
No more congressional chaplains, no more military chaplains, no more legislative prayers or 'invocations', change the motto to 'e pluribus unum', and remove the 'under God' corruption from the Pledge - that sort of thing.
Religious liberty already includes freedom FROM Government Religion in any way, shape, or form.
We just need to implement it.
Then we need to more forward to the separation of church and commerce, so that 'religious schools' have to follow all the same regulations as non-religious private schools, and 'religious hospitals' have to follow all the same regulations as non-religious hospitals.
We also have to get rid of 'Zombie' religious enterprises: https://scholarlycommons.law.northwestern.edu/cgi/viewcontent.cgi?article=1328&context=nulr#
We also need to get rid of the entire CONCEPT of a 'religious exemption' to a generally applicable statute. No, religion is not a 'get out of jail free' card with respect to any law you just don't happen to like. Just as the Mormons learned the hard way when we refused to give them a 'pass' on violating bigamy laws.
