That "hand scraping" (which it isn't) is going to telegraph through the LVP eventually.

But here's what you should do--Read the instructions on the LVP. Do what it says. Done.

It might just be a click-lock system. Remove a baseboard and investigate.

Megan , also read the warranty on the new product. It may not allow you to install over an uneven surface like the bamboo. Most floors require some prep work prior to installation.

I would go through the hassle of removing. In addition to the mentioned concerns I would be afraid the bamboo would rot being sandwiched between concrete and LVP.

The uneven surface of the bamboo has to be removed before you put down any rigid floor product (vinyl, laminate, floating cork, floating lino, hardwood, etc). To do that you need would need to SAND DOWN the surface...and then float. But I wouldn't recommend it. I would estimate $1-$2/sf for the sanding down of the surface (depends on whether or not there is aluminum oxide finish on the bamboo).

If you remove it, it can be removed (professional) and disposed of for $2/sf (or so). And teddytoo has a point: you do NOT want to sandwich a wood-like product between concrete and vinyl. The chance of it rotting is very high.

You can do it 'right' the first time or do it 'wrong' and then do it 'right' later on. The 'wrong' way is always more expensive (at the end of the day) than the 'right' way.

There is LVT with cork backing.

Demo. I'm never had bamboo flooring but, besides the concerns about making a moisture sandwich to rot and mold, I would be concerned about the expansion & contraction of the bamboo underneath the rigid overlay. What I understand about bamboo is that it is more wiggly than wood. Since you have engineered bamboo, probably doesn't move as much as a solid product would.

There are other reasons to remove it--like avoiding having to undercut door casings and shorten up doors. Removing baseboard or compromise by having it buried behind flooring. Probably other reasons that I'm not thinking of, too.

I would pry, scrape, whatever it takes to get it up & haul it to the firepit to get rid of it. There are going to be about a hundred responses telling you not to burn it. Fortunately, none of 'em know where I live. :-)

Thank you for all the advice. We have gotten mixed advice but will probably go through with removal. Hoping to demo ourselves So if anyone can advise on that... send my way

Boy, I would invest in rugs and be done. Unless it is in really bad condition which it looks good from photos. You could visually disguise with good rug and furniture plan. Post more photos if you can. I can do a mock up to show you how you could embrace what you have and save a ton of money, dust, time, disruption etc. etc.

I was told not to put my LVP over my old engineered hardwood due to the potential for rot. Also, it took 2 guys 2 days to demo my glue down floor, and they had a machine to help. I DO NOT recommend tackling that yourself. It was well worth the cost to hire it out. After they get the actual wood up, there will be glue left all over your slab which will need to be sanded down. It is a dusty awful mess, but worth doing it correctly
