VELCRO Brand Reusable Cable Ties, 100 Pack 6 Inch, Cord & Cable Management Straps for Electronics, Desk, Home Office & Workstations, Black

I think, as long as you didn’t damage any of the strands of the Dyneema, you should be fine. If you’re still worried about the integrity of the line. You could go a less invasive route and you could do is get some of that Velcro they use to wrap charging cables. Pretty cheap on Amazon but I actually really like that idea so I’ll probably copy you on that lol
