Alors non, tu peux utiliser ton mod sans soucis, BOSS n'est en rien oblligatoire.
Ce que fais BOSS, c'est réaorganiser l'ordre de tes mods, donc tu peux faire exactement la même chose toi même.
Installes ton mod et place l'esp à la fin de tes mods
Attention, sur Nexus il est écrit qu'il faut aussi installer le patch :

Installation
1. Install the mod and any mesh packs desired using your favorite mod management utility.
2. Activate the Dual Sheath Redux.esp. You may sort this mod anywhere you like as no vanilla forms are altered.
3. Run the installed Dual Sheath Redux Patch.jar located in Data/SkyProc Patchers/Dual Sheath Redux Patch (If using multiple SkyProc patchers, use SUM). This should be done AFTER all mods that add base weapons, staves, or shields are installed including other SkyProc mods such as Lootification. This step should be redone every time one of said mods are added, updated, or removed or you may get a CTD on startup for missing master files.
4. Click [Patch] on the patcher window, this may take a while depending on how many mods you have installed. Please be patient.
5. Activate the generated Dual Sheath Redux Patch.esp (this should be loaded after all mods listed above).
6. Run the game and enjoy!
Normalement si tu suis ça ce devrait marcher sans soucis
