Why this toolkit
These spells and attacks strip a weapon or press a save. The worked example is the Act 1 Voss silver-sword disarm. This is not a full feat list.
Command Drop
Command with the Drop option forces a weapon drop on a failed Wisdom save. Against Voss you also fight his advantage on Wisdom saves unless Heightened Spell cancels it.
Heat Metal
Heat Metal pressures a Constitution save and can make a creature drop a metal weapon. On the Voss route he does not get advantage on that Constitution save.
Fear
Fear can make a target drop what it is holding. The early-sword guide treats it as a weaker option than Honeyed Paws or a heightened Command, and notes Honour Mode limits.
Disarming Attack
Battle Master Disarming Attack (Ranged or Melee) needs a hit, then a Strength save. Manoeuvre DC comes from proficiency and ability scores only, so prep that helps the hit and the save matters more than stacking more spell DC gear.
For Voss, the early-sword guide pairs the attack with Lethargic after a Potion of Speed expires so the Strength save fails.
Honeyed Paws
Beast Master Ursa Major's Honeyed Paws auto-disarms on a hit with no saving throw. Invisible approach plus a Divination Portent die of 15+ is the published guarantee line for an unbuffed bear.
Dirty Trick: Flick o' the Wrist
The silver-sword item notes list Dirty Trick: Flick o' the Wrist among valid disarm tools. Use it when your party already runs that rogue trick; do not invent a success rate beyond a live roll in your save.
Named on the Silver Sword of the Astral Plane acquisition notes beside Command, Heat Metal, Fear, Disarming Attack, and Honeyed Paws.

Prep that actually moves the needle
For spell lines, the early-sword guide stacks Act 1 save-DC gear such as Melf's First Staff, The Protecty Sparkswall, and The Shadespell Circlet. For Honeyed Paws, invisible, Bless, Heroism elixir on the ground, and Phalar Aluve: Sing all help the attack roll. ASI or feats only matter here when they raise the spellcasting ability or keep concentration alive.
