Sure, but actually its pretty easy if you do it in the right way.
Step 1 - remove the small Horizontal trim piece at the top of the tailgate (inside of course) at the top of the window. No screws it' just pulls off and is held in place by 4 metal clips. Dead easy.
Step 2 - remove both vertical side trim pieces. Like step 1, there are no screws just metal clips and these pull off really easily.
Step 3 - the main interior boot trim. Remove the 4 screws that hold the trim in place (IIRC, 1 each inside both of the handle pull recesses, and a couple more near the triangle storage clip. With all screws removed, it's easier if you also remove the small trim pieces that cover the inner rear light cluster access areas on either side. These just unclip and come away. Removing these gives you somewhere to grab hold of the trim to pull. Now, the next bit isn't for the faint hearted but you need to start pulling the trim away from the body quite hard and sharply quickly in jabs. It won't come easily as the metal clips hold it very securely in place. The trim plastic is actually really resilient and is only now held in place by a shed load of metal clips, and it's doubtful you would damage the trim unless you really are ham fisted. If you start at one side, put you hand inside the light cover recess to removed above, and pull hard whilst holding the tailgate with the other, the clips will start to un-pop. When you have a few released, just keep working around the trim (it gets easier the more you remove.) Before the last clips are removed, support the trim with your other hand to stop it falling on the floor, and it will just fall away.
Re-assembly is an exact reversal of the above. Just make sure all the metal clips are in place on the plastic trims (some may have stayed in the tailgate, in which case remove them and slide them back onto the trims. Smack the trim with the palm of your hand over each of the clips, and you will hear it click into place and the trim will be hard up against the tailgate and won't have any play. Don't try (as I did 1st time) to install the upper trims before the lower main trim, as it's then next to impossible to get everything back in properly.
