Harsh seams harshing my vibe

New-ish to Blender and teaching myself with video tutorials. When I bake a normal map for my LP mesh I get really harsh lines where the seams are unless I select the 32 bit float option for my normal image in which case it’s perfect. The only issue is that unreal doesn’t seem to support the 32 bit float so when I import the mesh and textures to the engine, all the seams are back. Super frustrating. Sorry if I haven’t explained this well, I don’t know all the lingo. Thoughts?
