It is possible if you use VBS, but I would highly recommend against it. A Roth IRA is very precious long-term tax-free space for investments. You do NOT want to lose money in your Roth IRA because (a) you can't tax-loss harvest it and get a tax deduction and (b) you are limited in annual contributions, so if you lose money, you cannot "top it up" with a new contribution.
And I'll let others tell you about the folly of investing in individual stocks. If you wish to try it, I highly recommend that you use a taxable account where other taxpayers will help pay for your losses.
