Can I add custom mods to OptiFabricium without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (26.2). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.
