My VN Amazon has cable guides on the top tube for running a rear brake cable. I'm going to be fitting hydro brakes so I need to open them out to take the hose. Looks like it'll be easier to saw the end off the cable guide (and finish with a file) than to drill, given where the cable guides are.
Any particular tool I should be using/advice I should be heeding?

I’ve done similar mods to bikes over the years (as shop mech and for myself) and the easiest way I found was to use a compact head flexi drive for a dremel, similar to this one here, titanium is no more harder to drill than steel if you take your time and use high quality bits
I did exactly what somafunk suggests - albeit on carbon rather than titanium and with a cheapy demmel copy. No reason why grinding won't work on Ti, might take longer.
Scotroutes I’ve got one of those flexi things if you want to borrow I can post up.
I used a cheap Dremel copy from eBay for some mods on my Ti frame - don't expect the flexy shaft drive thing to last too long, mine gave out after a few hours - the drive cable broke

I did pretty much this on my old Setavento frame so I could run full-length gear cable to the rear mech. I just used a Dremel-type tool with a small hardened grinding head attachment and a lot of care then finished it with a small round file. Not difficult at all. I guess a flexible attachment could be a solution if you have clearance issues, but I was okay with that. I wouldn't be using a saw personally, a small slip could be messy.
On my Ti frame I had the lbs sell me a cable guide system that opens and closes to hold hydraulic hoses.
Best get phoning your lbs as dunno what they’re called now but do the trick nicely 👍
These?
Disc Brake cable guides. They screw into the existing guide and clamp around the hose.
